The answer is 4.
By the formula voltage = energy/charge.
Voltage = 60/15 = 4.
By the formula voltage = energy/charge.
Voltage = 60/15 = 4.

current=charge/time
power=voltage*current
p=qv/t
E=p*t=q*v
v=E/q=60/15=4 volts
power=voltage*current
p=qv/t
E=p*t=q*v
v=E/q=60/15=4 volts

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

Seriously mate? E = CV?
E = 0.5CV^2 is the formula.
V should be 2*2 volts.
E = 0.5CV^2 is the formula.
V should be 2*2 volts.

energy=charge*voltage
hence voltage=energy/charge
voltage=60/15=4volt.
hence voltage=energy/charge
voltage=60/15=4volt.

Condition 1: Energy = Charge * Voltage.
Then,
Voltage = Energy by Charge.
Then,
Voltage = Energy by Charge.

E = Pt.
P = VI=V*(Q/t)=VQ/t;
E = (VQ/t)*t=VQ;
E = VQ,
60 = V*15,
V = 4v.
P = VI=V*(Q/t)=VQ/t;
E = (VQ/t)*t=VQ;
E = VQ,
60 = V*15,
V = 4v.

Energy = Voltage * Current
60 = Voltage*15
Voltage = 60/15
Voltage = 4
60 = Voltage*15
Voltage = 60/15
Voltage = 4

Voltage=Energy/unit charge.
E=60J, q=15C.
V=joule/coulomb.
V=60/15=4V.
E=60J, q=15C.
V=joule/coulomb.
V=60/15=4V.
