When 12 A current flows through a circuit connected to a battery3 volts. When the current is flowing for 30 sec, calculate-a) R (resistance)b) W (work done)c) Q (electric charge)

Answer»
I= 12A
V = 3V
t = 30sec





a.) R=V/I =3/12=1/4 = 0.25ohm
b.)W = I×I×R×T=144×0.25×30=1080j
c.)Q =I ×t = 0.25 × 30= 7.5 C
