In the experiments you measure current,
voltage and resistance with a multimeter.
They are inexpensive, widely available
and can easily switch between a voltmeter,
amperemeter and ohmmeter.
A distinction is made between digital and
By using multimeters you are able to select
between several measured values
and measurement ranges.
For this you use, for most multimeters, a rotary switch...
Circuit symbol ammeter.
Circuit symbol voltmeter.
Circuit symbol ohmmeter.
An ammeter measures the electric current in
Ampere [A] and displays a positive reading when
the current flows from
the positive (+) to the negative (−) terminal.
A voltmeter measures the voltage in Volt [V]
and displays a positive reading when the electric potential
at the positive (+) terminal is higher than at the
negative (−) terminal.
An ohmmeter measures the electric resistance
in Ohm [Ω]
and always shows a positive reading.
Multimeters are available in two types,
analog and digital multimeter.
With measuring cables
do you connect them to the experiments...
