Question

28J work is done in moving a positive charge of 4C between two point. Find potential difference between the points

Answer 1

Work done in moving a point charge between two points on an .... Calculate the surface density a) 8C/m2 b) 0. .... Potential difference between the plates of a capacitor is 5.4V d) 11

Answer 2

Concept:

The potential difference between two places in a circuit is the difference in the amount of energy that charge carriers have.

Given:

Work done $W= 28J$

Positive charge $Q = 4C$

To Find:

Potential Difference

Solution:

Let the potential difference between two points be h, and is calculated as

$h= \frac{W}{Q}$

$h = \frac{28J}{4C}$

$h= 7 V$

The potential between the two points is $7V$.
