MCQ
Which is represented by the electric current :
- ACharge per unit volume
- ✓Charge per unit time
- CCharge per unit area
- DBoth $A$ .and $B$
✓
Answer
Correct option: B.
Charge per unit time
An electric current is a flow of electric charge. In electric circuits, this charge is often carried by moving electrons in a wire.
It can also be carried by ions in an electrolyte, or by both ions and electrons such as in a plasma.
It is the rate of charge flow past a given point in an electric circuit, measured in Coulombs/ second which is named Amperes.It is the charge per unit time.
