charge=15 voltage=? energy=60
so voltage=energy/charge
i.e.60/15= 4volt.

Energy and work done are same.

We khow that v=w/q.

Therefore 60/15=4.

CHETAN KUMAR said:   1 decade ago
ENERGY=(1/2)C*V*V
SO ENERGY=1/2Q*V
V=2*60/15
V=8 volt
????????????????

E=1/2*c*v^2 from this V=8v then which formula apply for this question?

Krishna said:   1 decade ago
q=c*v
q is charge,v is voltage,c is capacitence
60=15*v
Hence v=4volt

Apply energy is equals to hunkout charge and apply vootage. So e=qV.

Sasikumar said:   1 decade ago
Given energy=60j.
Charge=15c.
We know that Q=CV=>V=Q/C=60/15=4v.

As per jouleS formula VOLTAGE=ENERGY/CHARGE SUPPLIED.

V=60/15=4V.

Seetharaman said:   1 decade ago
V=IR
P=VI
V= E /Q

V= Voltage
E= Energy
Q= Charge Time

V=60/15=4V

Voltage = work done on unit charge.
V=W/Q or V=E/Q.
V=60/15.
V=4v.
