Power = volt * current.

Current is the amount of charge flowing through a cross section of the conductor in unit time here 't'.
So, current =15/t and the power is energy dissipates in time t so here 60/t.
60/t = volt*15/t.
volt = 4 volt.

Energy= Volt x Current x Time.
Charge = Current (const) x Time.
So, according to question V= 60 / 15 = 4 V.

E=Q * V.
60J = 15Q * V,
V = 60J ÷15Q,
V = 4V.

Simply, energy is equal to product of charge and voltage. So the answer is 4v.

E=q * v.
V=E÷q.
V =60÷15,
V=4 volt.

Energy=voltage*charge so voltage=energy/charge.
Where, energy=60, charge=15 voltage= ? 60/15= 4answer.

Here, E=V*Q.

Sushil said:   8 years ago
Q=60J
C=15C
V=?

we have,
Q=c*v
or,60=15*v
or,v=60/15

So,v=4V.

W = Vq.
V = W/q.
So, V = 60/15 = 4V.

Energy =voltage *charge.

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