Circuit Diagrams Practice

Front

What is a voltmeter?

Back

A voltmeter is an instrument used to measure the electrical potential difference (voltage) between two points in a circuit.

Front

What is a switch in a circuit?

Back

A switch is a device that can open or close a circuit, allowing or stopping the flow of electricity.

Front

How many pathways does a parallel circuit have for electrons to flow?

Back

A parallel circuit has two or more pathways for electrons to flow.

Front

What component is necessary to complete an electrical circuit?

Back

A battery is necessary to provide the electrical energy needed to complete a circuit.

Front

What characterizes a series circuit?

Back

In a series circuit, the same current flows through all components, and there is only one pathway for the current.

Front

What is a resistor?

Back

A resistor is a component that resists the flow of electric current, creating a voltage drop.

Front

What is the function of an ammeter?

Back

An ammeter is an instrument used to measure the current flowing through a circuit.

Front

What happens to the total resistance in a series circuit?

Back

In a series circuit, the total resistance is the sum of the individual resistances.

Front

What happens to the total current in a parallel circuit?

Back

In a parallel circuit, the total current is the sum of the currents through each pathway.

Front

What is the role of a battery in a circuit?

Back

A battery provides the necessary voltage to push the current through the circuit.
