Measuring Current

Measuring Current Use an ammeter to measure the current through the lamp. Draw a circuit diagram with the ammeter connected correctly.

How to set up an… Ammeter A

Measuring Current – Series Circuit Measure the current through: 1. The Battery 2. Bulb 1 3. Bulb 2

Measuring Current – Parallel Circuit Measure the current through: 1. The Battery 2. Bulb 1 3. Bulb 2

Measuring Voltage

Measuring Voltage Use a voltmeter to measure voltage across the lamp. Draw a circuit diagram with the voltmeter connected correctly

How to set up a… Voltmeter V
