purpose of a multimeter and understand how to set
the meter to the correct range before connecting to the circuit.
the advantages and disadvantages of analogue and digital
displays, and be able to read analogue and digital values.
the importance of polarity when connecting a meter
in a circuit.
a voltmeter is always connected in parallel with a
circuit component, and that an ammeter is always connected in series with
The current in all parts of a series circuit
has the same value and that the potential differences across components in
parallel are the same.
use of voltmeters and ammeters to determine the power
applied to a circuit. Recall that the RF output power (of an amplifier) is
less that the DC input power due to inefficiency.
