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 卤30 mC. What is the emf of the battery?

Short Answer

Expert verified

The emf of battery is3V.

Step by step solution

01

Given information

We have given that the capaciter batter is charged to 卤30mC.

We need to find the emf of the battery.

02

Explanation

In this problem, we have to find the emf of the battery, which means voltage of the battwery. UsingQ=CVformula to solve for V.

Q=CV鈫�V=QC鈫�30脳10-6C10脳10-6F=3V
