Question

6.Calculate the charge passing through
an electric bulb in 20 minutes if the value
of current is 200 milliampere.
O (a) 120 coulomb
O (b) 240 coulomb
O (c) 420 coulomb
O (d) 280 coulomb​

Answer 1

Answer:

240 coulomb

Explanation:

because its the answer

Answer 2

Answer:

(b)240 coulumb

Explanation:

it is given that I=200 mA =2×10to the power-1

t=20min=20×60sec=1200 sec

then Q=?

formula=I=Q/T

2×10to the power -1=Q/1200

2×10to the power -1×1200=Q

Q=240 coulumb
