Given - Current and time
Find - Charge
Solution - Charge is given by the formula = current*time
As per the known fact, 1000 mA = 1 A
Current in Amperes =
Performing multiplication and division
Current in Amperes = 0.2 Amperes
As per the known fact, 1 min = 60 seconds
2 mins = 60*2
Performing multiplication
2 mins = 120 seconds
Keep the values in formula to find the charge.
Charge = 0.2*120
Performing multiplication
Charge = 24 Coulombs.
Hence, 24 Coulombs charge has passed.
