Lesson: Voltmeters Science

In this lesson, we will learn how to use voltmeters in electric circuits to measure the potential difference across a component in the circuit.

Lesson Plan

Students will be able to

recall that the potential difference between two points in a circuit can be measured with a voltmeter,
recall what the circuit symbol for a voltmeter is,
recall that voltmeters must be connected in parallel to a circuit.

Q1:

The diagram provided shows an electric circuit consisting of a cell and a bulb.

Fill in the blank: In order to measure the potential difference across the bulb, a voltmeter must be connected with the bulb.

Q2:

The diagram shows an electric circuit. Which component of the circuit is the voltmeter measuring the potential difference across?

Q3:

The diagram shows an electric circuit. How many voltmeters are there in the circuit?
