Question

If potential difference of 10V causes a current of 2A to flow for 1 min, how much energy is transfered???? ​

Answer 1

P. D = 10V

I= 2 A

time = 1min= 60sec

I= Q/T

Q = 120 C

now work done = 120 × 10V

work done = 1200j

Answer 2

answer :   Energy, E = Power*Time  

= Voltage*Current*Time [Power = Voltage * Current]  

=10 V * 2A * 60 second  

=1200 Joule

explanation

Q = It

I = 2A

t= 1*60 = 60s

Thus, Q=2*60

=120 C

V=W/Q

V=10v

​Q=120 C

W=VQ

=10*120 joules

=1200 J

=1.2 KJ
