Question

When 12 A current flows through a circuit connected to abattery3 volts. When the current is flowing for 30 sec, calculate-
a) R (resistance)
b) W (work done)
c) Q (electric charge)

Answer 1

Answer:

a=1/4ohm= 0.25ohm

b=1080J

c=360 c

Explanation:

a.R=V/I=3/12=0.25ohm

b.W=Power×time

=Vi×t = 12×3×30= 1080J

c.Q= I×t = 12×30=360 coulomb
