Electricity: Calculator draws current for 5 minutes. How much charge flows through it?

A calculator draws a current of 0.0001 A for 5 minutes. How much charge flows through it?

Solution This solution is FREE courtesy of BrainMass!

The unit of current here is Amps which is equivalent to the number of coulombs of charge traveling through the circuit per second.

0.0001 A = 0.0001 C/s. To find the amount of charge over 5 minutes, multiply the current by the time.

Q = I*t = 0.0001C/s*5min*60sec/min = 0.03 Coulombs of charge.
