Chapter 30, Problem 19P(choose chapter or problem)
Consider the network of resistors shown in Fig. 19–40. 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 \(R_{1}=R_{2}=R_{3}=R_{4}=125 \Omega \text { and } V=22.0 \mathrm{~V}\). Determine the current through each resistor before and after closing the switch. Are your qualitative predictions confirmed?

Step by Step Solution
Step 1 of 11
APPROACH:
We use Ohm's law and the ideas for series and parallel connections to get the current and voltage in each case and we can also use the equations
