Question

What is the work done in moving a unit positive charge when the potential difference applied across the ends of the conductor is $10V$?

• A. $20J$
• B. $30J$
• C. $10J$
• D. $40J$

Answer 1

The correct option is C $10J$

Given:
Charge, $q=1C$
Potential difference, $V=10V$
Work done, $W=V\times q$
$\therefore W=10\times 1=10J$
