What is an electrical circuit?

Back

An electrical circuit is a closed loop that allows electric current to flow, consisting of a power source, conductors, and a load.

Front

What are the two main types of electrical circuits?

Back

The two main types of electrical circuits are series circuits and parallel circuits.

Front

In a series circuit, how does the current behave?

Back

In a series circuit, the current is the same through all components.

Front

In a parallel circuit, how does the voltage behave?

Back

In a parallel circuit, the voltage across each component is the same.

Front

What happens to the total resistance in a series circuit when more resistors are added?

Back

The total resistance increases when more resistors are added in a series circuit.

Front

What happens to the total resistance in a parallel circuit when more resistors are added?

Back

The total resistance decreases when more resistors are added in a parallel circuit.

Front

Why is copper commonly used for electrical wiring?

Back

Copper is commonly used for electrical wiring because it has high electrical conductivity.

Front

What is the purpose of insulation on electrical wires?

Back

The purpose of insulation on electrical wires is to prevent accidental contact with the conductive material and to ensure safety.

Front

What is an open circuit?

Back

An open circuit is a circuit that is not complete, preventing current from flowing.

Front

What is a closed circuit?

Back

A closed circuit is a complete circuit that allows current to flow.
