Measure current in series and parallel circuits, using a multimeter.
Measurement should include determining current, voltage, and resistance.
When working with a circuit,
- connecting the meter to the circuit should be done in the power-off condition
- negative reading(s) in a DC circuit means the leads are reversed
- current readings are always made in series with the circuit.
