Energy=voltage*charge so voltage=energy/charge.
Where, energy=60, charge=15 voltage= ? 60/15= 4answer.

E = qV.
V = E/q,
V = 60J/15C,
V = 4V.
E -> Energy.
q -> charge.
v -> voltage or potential difference.

v = voltage;
e = energy in joules = 60
Q = charge in couloumbs = 15

v = e/q => 60/15
*v = 4;

Q = 15c, and E = 60j given,

P = V*I.
dE/dt = P = V*I.
I = dQ/dt.
E = V*Q.
V = E/Q = 60/15 = 4.

Given:
J=60J
C=15C
V=?.

By applying the formula;
V =J/C.
we get.
V = 60/15.
Ans : A) V=4.

Volt* Coulombs/sec = Joules/sec.

Volt = Joules/Coulombs

= 60/15

= 4v.

Parag said:   1 decade ago
V=Q/C=60/15=4v

Q=ENERGY in joules=60
C=Charge in coulombs=15

joules/coulomb is voltage

Q = C*V

Q --> Energy
C --> Charge
V --> Voltage

V = Q / C

= 60/15 = 4 Voltage

Energy = 1/2(CV^2).

C = Charge.
V = Voltage.

V^2 = 2E/C.
V^2 = (40/3).

V = 3.6.
V = 4.

V = voltage.
E = energy.
C = charge.

As we know that E=C*V.

V = E/c.
V = 60/15.
V = 4.
