Question

24j of work is done in moving a charge q between 2 points having potential difference 12v. Find the value if charge q.

Answer 1

Work = Potential difference * Charge
Therefore,
q = Work / Potential difference = 24 Joules / 12 volts = 2 Coulombs

Hope this helps you !

Answer 2

Here,

• Work done = 24 J

• Potential Difference = 12 V

• Charge = ?

So,

Potential Difference = Work done / Charge

i.e. V = W/Q

Q = W/V

Q = 24/12

Q = 2 C

So, charge is 2 coulomb.
