Key Stage 4
Meaning
A joulemeter is an electronic device used to measure the energy transfer by electricity in a circuit.
About Joulemeters
- Joulemeters can be used to measure the energy transferred to an electrical component in a circuit.
- A joulemeter can be used measure the total energy transferred to an immmersion heater.
- A joulemeter can be made by attaching an ammeter in series with a component a voltmeter in parallel with the component and using a stopwatch to calculate the energy transferred using the equation
\(E=IVt\)
Where
\(E\) = The energy transferred (or electrical work done).
\(I\) = The current through the component.
\(V\) = The potential difference across the component.
\(t\) = The time over which energy has been transferred.
