Week 9: Electric Potential, Capacitance and Ohm's Law 1. (Schaum's 25.2) Ho the negative terminal of a 12 V battery? w much work is required to move an electron from the positive terminal to (Knight 21.4) A 20 nC charge is moved from a point where V-50V to point where v=-sov. How much work is done to move the charge? 2" (Knight 22. 64) If resistors 1 and 2 are connected to identical batteries, resistor 1 dissipates three times more power than resistor 2. What is their power ratio P/P2 when the same current is passed through each? 3.

Explanation / Answer

1) Going from positive terminal to negative terminal, one passes through a potential drop. In this case it is V = -12 V.

Then

W = qV

= (-1.6*10-19)(-12)

= 1.92 x 10-18 J
