Voltage = energy/charge = 60/15 = 4.

Energy = Charge * Voltage.
Voltage = Energy / Charge.
Voltage = Energy / Charge.

Volt* Coulombs/sec = Joules/sec.
Volt = Joules/Coulombs
= 60/15
= 4v.
Volt = Joules/Coulombs
= 60/15
= 4v.

E = 1/2*C*(V)^2
where E = Energy, C = Capicitanence, V = Voltage
where E = Energy, C = Capicitanence, V = Voltage

Energy = Voltage * Current
60 = Voltage*15
Voltage = 60/15
Voltage = 4
60 = Voltage*15
Voltage = 60/15
Voltage = 4

a] energy in power=60
b] current in charge=15
Formula : p=v*i
v=p/i
v=60/15
v=4v
b] current in charge=15
Formula : p=v*i
v=p/i
v=60/15
v=4v

ENERGY=(1/2)C*V*V
SO ENERGY=1/2Q*V
V=2*60/15
V=8 volt
????????????????
SO ENERGY=1/2Q*V
V=2*60/15
V=8 volt
????????????????

current=charge/time
power=voltage*current
p=qv/t
E=p*t=q*v
v=E/q=60/15=4 volts
power=voltage*current
p=qv/t
E=p*t=q*v
v=E/q=60/15=4 volts

E=qv
v=q/E
V=60/15=4V
v=q/E
V=60/15=4V

Here problem is about a single charge . if suppose +Ve charge has 15C charge and has energy 60 J than what is the value of potential generated by it.
we can not treat it as capacitor because in capacitor we treat the potential difference applied between plates.so kindly have it simple case. E = q . V = = 4 volt
