What is an open circuit?

Back

An open circuit is an incomplete circuit through which electricity will not flow.

Front

What is an electric circuit?

Back

An electric circuit is a path in which electrons from a voltage or current source flow, consisting of a battery, a wire, a load, and a switch to open and close the circuit.

What type of force is created when a battery is connected to a metal rod looped with metal wire?

Back

A magnetic force is created.

Front

How can an electric current be created in a coil of wire?

Back

An electric current can be created in a coil of wire by having a moving magnetic field.

Front

What is an electromagnet?

Back

An electromagnet is a type of magnet in which the magnetic field is produced by an electric current.

Front

What is a closed circuit?

Back

A closed circuit is a complete circuit through which electricity can flow.

Front

What is the role of a switch in an electric circuit?

Back

A switch is used to open and close the circuit, controlling the flow of electricity.

Front

What is the difference between series and parallel circuits?

Back

In a series circuit, components are connected end-to-end, so the same current flows through all components. In a parallel circuit, components are connected across common points, allowing multiple paths for current.

Front

What is electric current?

Back

Electric current is the flow of electric charge, typically measured in amperes (A).

Front

What is voltage?

Back

Voltage is the electric potential difference between two points in a circuit, measured in volts (V).
