Chapter 26: Q. 31 (page 738)

To what potential should you charge a 1.0mFcapacitor to store 1.0Jof energy ?

Short Answer

Expert verified

The required potential is 1.4kV.

Step by step solution

01

Given information 

We have given that 1.0mFcapacitor stores energy 1.0Jof energy.

We need to find the potential.

02

Explanation

The formula for voltage. We're given U(1J),andC(1渭F)

U=12CV2鈫�V=2UC

Using the given values in the above formula, we get

localid="1648664182926" V=(2)(1)J1脳10-6=1.4V.
