current of 0.2 A is drawn by filament for 10 minutes .
hence, current , I = 0.2A
time , t = 10 minutes = 10 × 60 = 600 sec
we know,
current is the rate of change of charge per unit time in a wire.
e.g., I = Q/t => Q = It
so, Q = 0.2 × 600 = 60C
hence, amount of electric charge = 60C
hence, current , I = 0.2A
time , t = 10 minutes = 10 × 60 = 600 sec
