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

V = J/C.
V = 60/15,
V = 4v.
V = 60/15,
V = 4v.

We know that:
V= w/Q.
Written as this formula;
V=j/c.
= j= 60,
=C= 15,
= 15/60,
V=4 = Answer.
V= w/Q.
Written as this formula;
V=j/c.
= j= 60,
=C= 15,
= 15/60,
V=4 = Answer.

Joule is energy gained by 1 coulomb of charge when placed in a potential difference of 1 volt.
Hence, Joule = Coulomb times Volt.
Given, Energy =60 J, Charge = 15 C therefore Voltage =(60/15) = 4 Volts.
Hence, Joule = Coulomb times Volt.
Given, Energy =60 J, Charge = 15 C therefore Voltage =(60/15) = 4 Volts.

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

Q/C = V.
60/15 = 4.
60/15 = 4.

Q = C * V.
V = Q/C.
4 = 60/15.
V = Q/C.
4 = 60/15.

Here we should not take energy as magnetic or capacitive since it is not mentioned.
E=Pt and P=VI=V* (Q/t).
=>E=V*Q.
=>V=4---->answer.
E=Pt and P=VI=V* (Q/t).
=>E=V*Q.
=>V=4---->answer.

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.
