Electrical Circuits

Front

What is a material that does NOT let electricity pass through it called?

Back

An electrical insulator.

Front

Why is copper commonly used for electrical wiring?

Back

Because copper conducts electricity.

Front

What is the purpose of the plastic covering on electrical wiring?

Back

To make it safe.

Front

What can work as an energy source in an electrical circuit?

Back

Battery.

Front

What is an open circuit?

Back

A circuit that does NOT allow electricity to flow.

Front

What is the role of a conductor in an electrical circuit?

Back

To allow electricity to flow through it.

Front

What is the difference between a series circuit and a parallel circuit?

Back

In a series circuit, components are connected end-to-end, while in a parallel circuit, components are connected across common points.

Front

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

Back

The total resistance increases.

Front

What is Ohm's Law?

Back

Ohm's Law states that the current through a conductor between two points is directly proportional to the voltage across the two points.

Front

What is the unit of electrical resistance?

Back

Ohm.
