Question
Electrical current is measured in which of the following units?
Answer Options
- A) Volts
- B) Watts
- C) Ohms
- D) Amperes
Correct Answer: D
Explanation
Electrical current is the measure of the rate of electron flow in an electric circuit (T5A03). This is analogous to the flow rate of water in a pipe. The standard unit used to quantify this flow is the Ampere (A).
Amperes tell you how much electrical charge (electrons) is moving past a point per second. The other common units measure voltage (Volts - the electrical pressure), power (Watts - the rate of energy usage), and resistance (Ohms - the opposition to flow).
