Question

a charge of 7.0 C flows along a wire in 5.0 minutes

calculate the current in the wire ?​

Answer 1

Answer:-

• Charge=Q=7C
• Time=t=5min

Convert it to seconds

• 1min=60s
• 5min=5×60=300s
• Current=I=?

We know that

$\boxed{\sf I=\dfrac{Q}{t}}$

$\\ \tt\longmapsto Current=\dfrac{7}{300}$

$\\ \tt\longmapsto Current=0.02A$

Note:-

SI unit of Current is Ampere(A)
