PHY 102 Capacitors and Capacitance Objective Question
Take CBT

Question

What is the work required to carry an electron (q = -1.6×10⁻¹⁹ C) from the positive terminal to the negative terminal of a 12 V battery?
Options
A 1.9 × 10⁻¹⁸ J
Correct Answer
B 1.9 × 10⁻¹⁹ J
C 1.9 × 10⁻¹⁷ J
D 1.9 × 10⁻²⁰ J
Correct Answer

Option A is the correct answer.

Detailed Explanation

W = qV = (-1.6×10⁻¹⁹ C)(-12 V) = 1.92 × 10⁻¹⁸ J. The negative signs cancel.

Hint

Work = charge × potential difference.
