E=QV
V=E/Q
V=60/15
V=4
Where,
E=energy measured in joules
Q=charge measured in coulomb
v=voltage measured in volt
V=E/Q
V=60/15
V=4
Where,
E=energy measured in joules
Q=charge measured in coulomb
v=voltage measured in volt

power=energy/time
power=voltage*current
so v*i/t =energy
charge=i*t
given charge=15c
v*15=60
voltage is 4v.
power=voltage*current
so v*i/t =energy
charge=i*t
given charge=15c
v*15=60
voltage is 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.

Energy = charge * voltage
here Voltage =?
voltage = Energy / charge
= 60 / 15 = 4
Hence voltage = 4V
here Voltage =?
voltage = Energy / charge
= 60 / 15 = 4
Hence voltage = 4V

Voltage = (Work done/Charge).
Energy is ability to do work.
So, Voltage = (w/q).
= (E/q).
= 60/15.
= 4 volt.
Energy is ability to do work.
So, Voltage = (w/q).
= (E/q).
= 60/15.
= 4 volt.

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
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
v=e/q
v=60/15
v=4v

Energy= Volt x Current x Time.
Charge = Current (const) x Time.
So, according to question V= 60 / 15 = 4 V.
Charge = Current (const) x Time.
So, according to question V= 60 / 15 = 4 V.

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.

We know that, energy = voltage*charge.
So charge = energy/voltage.
Let, V = 60/15 = 4v.
Answer: 4v.
So charge = energy/voltage.
Let, V = 60/15 = 4v.
Answer: 4v.
