Question

The work done in moving a unit positive charge is $25J$.
What is the potential difference applied across the ends of the conductor?

• A. $25V$
• B. $35V$
• C. $20V$
• D. $40V$

Answer 1

The correct option is A $25V$

Given:
Charge, $q=1C$
Work done, $W=25J$
Potential differnce, $V=\frac{W}{q}$
$\therefore V=\frac{25}{1}=25V$
