Question
Which instrument is used to measure electric current?
Answer Options
- A) An ohmmeter
- B) An electrometer
- C) A voltmeter
- D) An ammeter
Correct Answer: D
Explanation
Electric current is the measure of the rate of electron flow (T5A03), and its unit is the Ampere (T5A01). The instrument used to measure current is an ammeter.
To take a measurement, the ammeter must be inserted directly into the path of the circuit (in series, T7D03) so that the entire current flow passes through its low-resistance internal coil or shunt.
