Chapter 26: Q. 24 (page 738)

A switch that connects a battery to a 10 mF capacitor is closed. Several seconds later you find that the capacitor plates are charged to $\pm$ 30 mC. What is the emf of the battery?

Short Answer

Expert verified

The emf of battery is $3 V$ .

Step by step solution

Given information

We have given that the capaciter batter is charged to $\pm 30 m C$ .

We need to find the emf of the battery.

Explanation

In this problem, we have to find the emf of the battery, which means voltage of the battwery. Using $Q = C V$ formula to solve for $V$ .

$Q = C V \to V = \frac{Q}{C} \to \frac{30 \times 10^{- 6} C}{10 \times 10^{- 6} F} = 3 V$
