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.
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.
The diagram shows an electric circuit. Which component of the circuit is the voltmeter measuring the potential difference across?
The diagram shows an electric circuit. How many voltmeters are there in the circuit?
