Electricity

Front

The SI unit for resistance is the _______________________________.

Back

Ohm

Front

Materials that resist the flow of electric current are called _____________.

Back

insulators

Front

____________________________ is a continuous flow of electric charges (electrons).

Back

Back

Voltage

Front

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

Back

Conductors allow electric current to flow through them easily.

Front

What is the role of an insulator in an electric circuit?

Back

Insulators prevent the flow of electric current.

Front

What is the relationship between voltage, current, and resistance?

Back

Ohm's Law states that V = I * R, where V is voltage, I is current, and R is resistance.

Front

What happens in a circuit if the positive terminal of the battery is not connected?

Back

The circuit will not work because it is not a closed loop.

Front

What is electric current measured in?

Back

Amperes (A) or Amps.

Front

What is voltage measured in?

Back

Volts (V).
