Energy =Charge*voltage
=>voltage=energy/charge
=>V=60/15=4
Hence 4V is the answer

Voltage is the electric potential energy per unit charge.

V = E/Q
V = 60/14
V = 4 volt

P=W/t
Therefore W=P*t
And P=V*I
So W=V*I*t
Now q=I*t
Therefore W=V*q
So V=W/q=60/15=4V

a] energy in power=60
b] current in charge=15

Formula : p=v*i

v=p/i

v=60/15

v=4v

P=I^2 R.

I=V/R from ohm law,

Then P=V^2R.

R=V/I.

We get V=P/I.

V=60j/15c.

=4V.

Voltage is work done in moving 15C of charge.

Hence v = energy/charge = 60/15 = 4v.

To find voltage.

Given Energy = 60j.

Charge = 15.

By formula V = E/C = 60/15 = 4.

Energy = Voltage*Charge (Current).

60 = Voltage*15.

60/15 = Voltage.

4 = Voltage.

Energy =voltage *charge.

Therefore,
Voltage=energy/charge.
Voltage=60J/75c.
=4v.

Since Q = CV given that Q = 60 and C = 15.

So answer is V = Q/C = 60/15 = 4v.
