Voltage = Energy/degree
=60/15
=4
=60/15
=4

V=I*R
V=60*15
V=900
V=60*15
V=900

As we all know power= voltage*current,
And
Power= work/time , current= charge/time
So,
Work= voltage*charge
NOW 60= VOLTAGE*15
SO, VOLTAGE= (60/15)= 4V.
And
Power= work/time , current= charge/time
So,
Work= voltage*charge
NOW 60= VOLTAGE*15
SO, VOLTAGE= (60/15)= 4V.

60J means 60 watt in 1 sec. In 1 sec current is I=Q/t=15/1(Q is charge and t is time)=15 amps.
Again Watt=Voltage*Current
Therefore,60=V*15(V is voltage)
V=4V
Again Watt=Voltage*Current
Therefore,60=V*15(V is voltage)
V=4V

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.

I agree that energy is the multiplication of voltage and charge.

Given data
E=60 j , Q = 15.
we know that
Energy = charge*voltage.
Then,
Voltage = Energy/charge.
Voltage = 60/15.
V = 4v.
E=60 j , Q = 15.
we know that
Energy = charge*voltage.
Then,
Voltage = Energy/charge.
Voltage = 60/15.
V = 4v.

Voltage is workdone in moving 15C of charge hence 60/15=4V.

Voltage is work done in moving 15C of charge.
Hence v = energy/charge = 60/15 = 4v.
Hence v = energy/charge = 60/15 = 4v.

E = Q*V. (ENERGY=charge*voltage).
V = Q/E. (voltage=ENERGY/charge).
Q = 60, E = 15.
V = 60/15.
V = 4.
V = Q/E. (voltage=ENERGY/charge).
Q = 60, E = 15.
V = 60/15.
V = 4.
