Current Electricity (copy Liero)

Front

What is an open circuit?

Back

An open circuit is a broken circuit that does not allow electrons to flow.

Front

What happens to current when resistance increases?

Back

When resistance increases, the current slows down.

Front

What is needed to increase current in a circuit with resistance?

Back

You will need more voltage to speed up the current.

Front

What is the movement of electrons called?

Back

The movement of electrons is called electric current.

Front

What does it mean for an object to have a net negative charge?

Back

It means the object contains more electrons than protons.

Front

What type of materials are insulators?

Back

Insulators are materials that provide high resistance, preventing electrons from moving easily.

Front

What is voltage?

Back

Voltage is the electrical potential difference that drives current through a circuit.

Front

What is current?

Back

Current is the flow of electric charge, typically measured in amperes.

Front

What is resistance?

Back

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

Front

What is a closed circuit?

Back

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