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

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.

The answer is 4.

By the formula voltage = energy/charge.

Voltage = 60/15 = 4.

E = I^2R
E = I * IR
E = I * V.
(V=E/I )
Joules=Coloumb * Volts.
(Volts=Joules/ Coloumb).

Here,
60 = 15 * Volts.

Volts = 60/15,
Volts = 4.

V = q/c.
So 60/15 = 4ans.

It is easier to understand if you say the charge flows during a time t, then the current is 15/t Amps. The power available is 60/t Watts.

Watts = Volts * Amps.
60/t = V * 15/t.
V = 4.

60/15 = 4 simple.

Watts = Volts * Amps,
60/t = V * 15/t,
V = 4.
