Question:

In the circuit shown in Fig. E26.18, ε = 36.0 V, R1= 4.00 Ω, R2= 6.00 Ω, and R3= 3.00 Ω.

(a) What is the potential difference Vab between points a and b when the switch S is open and when S is closed?

(b) For each resistor, calculate the current through the resistor with S open and with S closed. For each resistor, does the current increase or decrease when S is closed?
