A.) What is the potential difference between a and b? B.) What is the equivalent resistance of the circuit?

2. The capacitor in the figure below is initially uncharged and the switch, in position c, is not connected to either side of the circuit. The switch is now flipped to position a for 10 ms, then to position b for 10 ms, and then brought back to position c. What is the final potential difference across the capacitor? 12 V 150 Ω ww a b 40 μF 150 Ω

An electric circuit consisting of wires, batteries and resistors is shown. All currents have been labeled and assigned directions.   a.) Which statement is a correct expression of Kirchhoff's Junction Rule for currents with labels and directions assigned on the above figure?    I1 + I2 + I3 = 0       I1 - I2 + I3 = 0       None of these statements are correct.       I1 - I2 - I3 = 0       I1 + I2 - I3 = 0    b.) Which statement is a correct expression of Kirchhoff's Loop Rule for the sum of voltage changes for the large outer loop?     18.0 V - (80.0 Ω)I1 + 12.0 V + (50.0 Ω)I3 + (80.0 Ω)I3 = 0       18.0 V - (80.0 Ω)I1 - 12.0 V + (50.0 Ω)I3 + (80.0 Ω)I3 = 0       None of these statements are correct.       18.0 V - (80.0 Ω)I1 + 12.0 V - (50.0 Ω)I3 - (80.0 Ω)I3 = 0       -18.0 V - (80.0 Ω)I1 - 12.0 V + (50.0 Ω)I3 + (80.0 Ω)I3 = 0       18.0 V - (80.0 Ω)I1 - 12.0 V - (50.0 Ω)I3 - (80.0 Ω)I3 = 0
