Chetan kumar you are not right. Thanks to all of you.

Energy and work done are same.

We khow that v=w/q.

Therefore 60/15=4.

Prasant said:   1 decade ago
e=v*i*t
q=i*t
e=v*q
v=e/q
q is charge
i is current
e is energy
v is voltage generated
t is time of charge flow

We know that charge Q=E/V
v=e/q
v=60/15
v=4v

Ramesh nirjogi said:   1 decade ago
v=w/q
v=60/15
v=4v
or
p=vi
p=v(q/t)
e=pt=vq

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

Devaki said:   1 decade ago
Energy = charge * voltage

here Voltage =?

voltage = Energy / charge

= 60 / 15 = 4

Hence voltage = 4V

Sireesha said:   1 decade ago
power=energy/time

power=voltage*current

so v*i/t =energy

charge=i*t
given charge=15c

v*15=60
voltage is 4v.

Sunitha said:   1 decade ago
Here voltage=?

Voltage=energy/charge.

Hence v=60/15=4v.

We know the current i=15
energy is 60 j,
hav to find the voltage?

v=energy/current
=60/15
=4V
