Question

A total charge of $90$ coulombs flows in a conductor during a time of $5$ minutes. What is the strength of current in the conductor?

• A. $0.2A$
• B. $0.3A$
• C. $0.4A$
• D. $0.5A$

Answer 1

Answer: (B)

$0.3A$

$Q=90C$

$t=5min=5\times 60=300s$

Current$=I=\frac{Q}{t}=\frac{90}{300}$

$⟹I=0.3A$

Answer-(B)
