Learning outcomes part 10
-
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
a component.
-
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.
