Question:
Consider the network of resistors shown in Fig. 19-52. Answer qualitatively:
(a) What happens to the voltage across each resistor when the switch S is closed?
(b) What happens to the current through each when the switch is closed?
(c) What happens to the power output of the battery when the switch is closed?
(d) Let R1 = R2 = R3 = R4 = 155 Ω and V = 22.0 V. Determine the current through each resistor before and after closing the switch. Are your qualitative predictions confirmed?
