Hey
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

w=60J q=15C

v= w/q

v=60/15
v=4v

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

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

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

a] energy in power=60
b] current in charge=15

Formula : p=v*i

v=p/i

v=60/15

v=4v

Energy = Voltage * Current

60 = Voltage*15

Voltage = 60/15

Voltage = 4

E = 1/2*C*(V)^2

where E = Energy, C = Capicitanence, V = Voltage

Volt* Coulombs/sec = Joules/sec.

Volt = Joules/Coulombs

= 60/15

= 4v.
