T=0.2A V=220V T=1hr Covert 1 hour in second T=3600 sec Q=? I=Q/T Q=I×T Q=0.2×3600 Q=720C

Given:

The current drawn by the electric bulb, I = 0.2 A (Ampere)

The voltage, v = 220 v (Volts)

The amout of electric charge for one hour, Q = ? (Coulomb)

Solution:

Time, t = 1h

= 3600 s

We know that,

= 720 C

Amount of electric charge for one hour, Q = 720 Coulomb.
