Question

The quantity of a charge that will be transferred by a current flow of $20 \,A$ over $1 \,hour\, 30$ minutes period is

• A. $10.8 \times 10^3 \, C$
• B. $10.8 \times 10^4 \, C$
• C. $5.4 \times 10^3 \, C$
• D. $1.8 \times 10^4 \, C$

Answer 1

Answer: (B)

Time period, $t =1 hr 30 min =1.5 \times 3600=5400 s$
Current flowing, $I =20 A$
$\therefore$ Charge transferred, $q = It =20 \times 5400=10.8 \times 10^{4} C$
