Time period, t =1 hr 30 min =1.5 × 3600=5400 s Current flowing, I =20 A ∴ Charge transferred, q = It =20 × 5400=10.8 × 104 C

Q. The quantity of a charge that will be transferred by a current flow of $20 A$ over $1 h o u r 30$ minutes period is

$10.8 \times 1 0^{3} C$

$10.8 \times 1 0^{4} C$

$5.4 \times 1 0^{3} C$

$1.8 \times 1 0^{4} C$

Time period, $t = 1 h r 30 min = 1.5 \times 3600 = 5400 s$
Current flowing, $I = 20 A$
$∴$ Charge transferred, $q = I t = 20 \times 5400 = 10.8 \times 1 0^{4} C$
