Electricity Basics Flashcard

Front

What is a conductor?

Back

A conductor is a material that allows electric charge to flow easily through it. Examples include metals like copper and aluminum.

What is an insulator?

Back

An insulator is a material that does not allow electric charge to flow easily. Examples include rubber, plastic, and glass.

Front

What is a parallel circuit?

Back

A parallel circuit is a type of electrical circuit where there are multiple paths for the electric current to flow. If one path is broken, current can still flow through the other paths.

Front

What is a series circuit?

Back

A series circuit is a type of electrical circuit where there is only one path for the electric current to flow. If there is a break in the circuit, the current stops flowing.

Front

What happens if a circuit is open?

Back

If a circuit is open, it means there is a break in the circuit, and electric current cannot flow.

Front

What happens if a circuit is closed?

Back

If a circuit is closed, it means there are no breaks, and electric current can flow freely.

Front

What is voltage?

Back

Voltage is the electrical force that pushes electric charges through a circuit. It is measured in volts.

Front

What is current?

Back

Current is the flow of electric charge in a circuit, measured in amperes (amps).

Front

What is resistance?

Back

Resistance is the opposition to the flow of electric current, measured in ohms.

Front

What is a short circuit?

Back

A short circuit occurs when there is a low-resistance connection between two points in a circuit, causing excessive current to flow.
