So I have attached an image named “Task” which gives me full explanation on how the lab report should be.

First you should watch a 2 video which does the lab physically on the video.

Secondly you can download the images “LabManual1-10” and read them for the lab report.

Lastly this is how the paper should be. I need the report to follow the “task” image and the instructions I give below.

1) First page just cover

2) Second page will be the introduction, All you have to do for this page is to put the INTRO on the lab manual on your own words. DO NOT COPY AND PASTE

3) Third page will be similar to second page however you have to put the procedure section in the lab manual in your own words. DO NOT COPY AND PASTE

4) please follow the “task” image, the part about Data/Analysis

5) please follow the “task” image, the part about Conclusion

Assorted leads LOW VOETNE BORER SALE 2-2 LABORATORY OBJECTIVES To understand series and parallel circuit connections and how to connect meters for reading current and voltage. INTRODUCTION In a series circuit there is only one path for the flow of charge or current as it leaves the positive (+) side of a power supply, travels through the circuit and returns to the negative (-) side of the power supply. Therefore, in a series circuit all of the current from the power supply travels through each circuit element lamps, carbon resistors, etc.). In a parallel circuit there are two (or more) paths for the current to flow through the cir- cuit. When the current coming from the power supply reaches the branch in the circuit, or node, it splits. Some current travels through one branch, and the rest travels through the other branch of the circuit. An ammeter can be connected in series with a circuit to read the amount of current in amps or milliamps) flowing through that branch of the circuit. An ammeter is always connected in series with the circuit element whose current you are measuring so that each has the identical current. The ammeter has a very low resistance so that the meter causes only a minimal disturbance in the circuit. A voltmeter is used to measure electrical potential difference (in volts or millivolts) between two points in a circuit; for example, across (from one end to the other end) a circuit element. A voltmeter is always connected in parallel with the circuit component whose potential difference you are measuring. The resistance of a voltmeter is very high so that it uses a miniscule current, and does not disturb the rest of the circuit. Electrical circuits are represented by schematic diagrams. These diagrams show which circuit elements are connected to which, but they do not indicate the physical position of the circuit elements. The schematic diagrams below are all the identical circuit. This circuit shows two incandescent light bulbs connected to a variable voltage source and a voltmeter. The straight lines represent wires. Notice that, in every case, one side of the top light bulb touches the positive side of the variable power supply and the other side touches the other light bulb. CHUC FIGURE 2-1.

PROCEDURE In each part of this experiment there is a diagram of the circuit you should connect with the circuit elements at your workstation. In each section of the instructions there are a few questions and directions of what you should observe. In order to make these observations, resistors are needed. The problem with ordinary resistors is that there is no visual clue to show if a current is flowing in the circuit or not. In order to observe what the electrical current is doing, this experiment uses light bulbs in place of resis- tors. Electrically we are only interested in the bulb’s resistance. For this reason we shall represent the bulbs with resistor symbols in the circuit diagrams. To connect a circuit, start at one point in the diagram, e.g., the positive side of the power supply, and connect a wire representing the first line in the schematic diagram. To the other end of this wire connect whatever circuit element that the schematic diagram calls for. From the other side of the first circuit element use a second wire to connect it to the next element in the schematic diagram. Continue this process until you reach the nega- tive side of the power supply. If there are branches to the circuit connect one complete branch first. Then start at a circuit node and connect the next branch of the circuit. Have your partner check your circuit to be sure it is connected correctly. Unless oth- erwise instructed, the power supply is turned on after the electric circuit has been checked with the knob fully counterclockwise, then slowly increase the voltage (clock- wise rotation of the knob) until you can see the effect you wish to observe. This proce- dure avoids unpleasant surprises. Sometimes it happens that the meter shows nothing and the light bulbs do not light up when you turn on the power supply. Check to see that the light bulbs are firmly screwed into their sockets. Then visually follow the circuit path, wire by wire, making sure that each connects to the correct circuit element. Try to determine which circuit element could be connected incorrectly before calling your instructor for help oogle 2-4 A-1 Part A: Series Circuits Connect the series circuit shown in Figure 2-3. Be sure that you connect the “a” and “c” leads to the bottom two terminals of the power supply. They are labeled DC; the AC electricity that is found on the upper two connectors can damage your meter. Increase the voltage slowly by turning the knob clockwise until the light bulbs start to glow. a. Unscrew one of the two bulbs from its socket. What happens? Replace the bulb. Other sulb off b.

This section should discuss the theory for the lab and how we are going to verify that theory in the lab for that week. 2) Procedure: 1 page. This section details how the data collection was performed. This will be in the third person and will detail the data collection you saw in the videos. You are free to include diagrams as well (which I will count towards the full page requirement for the procedure). 3) Data/Analysis: Varies in length depending on the lab (no set length). This section will include data tables (clearly labeled), graphs (clearly labeled), sample calculations (one for each type), and the answers to the questions that are asked of you in the lab manual for that week’s lab. THIS IS THE MOST IMPORTANT SECTION! Most of the points for the lab reports are assigned to this section. BE THOROUGH! 4) Conclusion: 3-4 paragraphs. This section summarizes the results for the experiment. You will also include any sources of error that you can think of for that experiment (not required, but encouraged). 2-6 A-2 Connect the left circuit in Figure 2.5 with the ammeter and two light bulbs. Turn on the power supply so that the bulbs glow. Measure and record the cur- rent going into the top bulb and label this current I. Draw the schematic dia- gram for this circuit. The symbol for an ammeter is A). DO NOT TURN THE POWER SUPPLY KNOB! Remove the banana plug from the positive terminal of the power supply. This effectively cuts off the current in your circuit. Connect the second of the circuits shown in Figure 2-5, and reinsert the banana plug into the power supply. Measure and record the current in this circuit and label this current , Draw the schematic diagram for this circuit Turn off the power supply and disconnect the circuit. Connecting a Voltmeter A voltmeter is always connected in parallel with the circuit element, the potential difference across which you want to measure. In making such a circuit it is possible to stack two banana plugs so that two wires are connected to the same point in the circuit (see Figure 2-9). Notice how the voltmeter leads are connected to the meter in Figure 2-6. In order to have the proper signs in your meter readings it is necessary to have the V/A connection Vestas unearest to the positive connector of the power supply.

Part B: Parallel Circuits In a parallel circuit, there is more than one path for the current to take and the electri- cal potential difference along each path is the same. The current splits at the first node: part going one path, part going through the other path. The currents rejoin at the second node. FIGURE 2-8. The schematic diagram for a parallel circuit.
