# Worksheet: Current and Charge

In this worksheet, we will practice defining electrical current and converting between a current in amperes and the number of coulombs of charge delivered.

**Q1: **

For how long would a current of 0.15 A need to be sustained to deliver a charge of 12 C?

**Q2: **

After 30 s, the total charge that passes a specific point in a circuit is 12 C. What is the current?

**Q3: **

What is the equation which expresses the total charge delivered by a current in a period of time ?

- A
- B
- C
- D
- E

**Q4: **

A current of 0.2 A passes through a wire for a period of 60 s. Calculate the total charge delivered by the wire.
