In this worksheet, we will practice defining electrical current and converting between a current in amperes and the number of coulombs of charge delivered.
For how long would a current of 0.15 A need to be sustained to deliver a charge of 12 C?
After 30 s, the total charge that passes a specific point in a circuit is 12 C. What is the current?
What is the equation which expresses the total charge delivered by a current in a period of time ?
A current of 0.2 A passes through a wire for a period of 60 s. Calculate the total charge delivered by the wire.
Which of the following electrical currents would deliver the greatest charge?
- A 0.10 A for 35 s
- B 0.05 A for 60 s
- C 1.0 A for 1.0 s
- D 0.25 A for 15 s
- E 20 A for 0.15 s
