If a toy fan is connected across a battery for 2 minutes and we know that a charge transfer of 120C takes place then find out the current in the circuit for that period of time.


Open in App
Solution

Step 1: Given

Charge transfer, Q=120C

Time taken, t=2×60s=120s

Step 2: Determine the rate of flow of current

Current in a circuit is given by,

I=Qt=120120=1A

Hence, the current in the circuit is 1A.
