Find the equivalent resistance between points 1 and 2 below. 10: 15. 1n3 3452 511 2 2 252 24 2.5 Ω 6.5 Ω 4.0Ω 5.0Ω 16 Ω The capacitor shown in the diagram is initially uncharged and the switch S is open. S R C Suppose that 4 circuits with different values of emf, R, and C are given. Circuit 1: emf = 18V, R = 3 Ohms, C = 1 uF Circuit 2: emf = 18V, R = 6 Ohms, C = 9 uF = Circuit 3: emf = 12V, R = 1 Ohms, C = 7 uF Circuit 4: emf = 10V, R = 5 Ohms, C = 7 uF Rank the circuits according to the time after switch S is closed for the capacitors to reach half their final charges, least to greatest. 2, 4, 3, 1 O 3, 1, 2,4 O 1, 2, 3, 4 O 4, 2, 1,3 1, 3, 4,2 Question 3 4 pts When you have multiple resistors in parallel with each other, the equivalent resistance is O None of these smaller than the resistance of any of the resistors O larger than that of any other resistor the same as the resistance of one of the resistors Question 4 The light bulbs in the circuit are identical. When the switch is closed, what happens? 12 V A 12 V B A gets brighter and B gets dimmer intensity of b
