Measuring Voltage

In this section we will find out how to measure
voltage with a multimeter:-

Open the "using a multimeter" link at the top of this screen
and carefully read sections 1 and 2. Then read the part
headed "Measuring Voltage" before reading on.

The multimeter below has had its centre dial turned round to
read up to 20 Volts. We can now use it to check the voltage
(potential difference) across the two terminals of our single
battery.

 

Move the battery
between the
meter's red (+) and
black (-) probes.
The meter will
then display the
voltage of the
battery.
