Measuring electric current

Electric current is measured by an ammeter.

The following are some of the rules that must be observed when measuring electric current:

How to Measure Electric Current

To measure electric current in a circuit, follow these important rules:

1. Use an Ammeter – An ammeter is the instrument used to measure electric current.
2. Connect in Series – The ammeter must be connected in series with other components in the circuit. This ensures that the current flows through the ammeter.
3. Correct Wiring – Make sure all wires are properly connected in their respective positions. Wrong connections can lead to incorrect readings or even damage the ammeter.
4. Record at Equal Intervals – When taking readings, ensure that measurements are recorded at equal voltage intervals for accuracy.

Important Safety Tips

• Never touch live wires with bare hands.
• Do not exceed the ammeter's maximum current limit.
• Always turn off the power before adjusting the circuit.
