E1: Electric Circuits — C level

Here is a diagram of a circuit. It has:

• A DC power supply
• A lamp
• A switch

Do

Make the circuit.

If you want to measure the electric current in the lamp, you must put an ammeter so that the electricity goes through the ammeter on its way to the lamp.

The ammeter is in series with the lamp.

Here is a diagram showing the ammeter added in.

Do

Make the circuit. Show your teacher. Answer any questions they have.

If you want to measure the voltage across the lamp, you must put a voltmeter so that its is connected to both terminals of the lamp.

The voltmeter is in parallel with the lamp.

Here is a diagram showing the voltmeter added in.

Do

Make the circuit. Show your teacher. Answer any questions they have.

You can measure the voltage and the current at the same time. Here is a diagram showing how to do that.
