Front

What happens to the lights in a series circuit if one bulb is removed?

Back

The rest of the lights will go out.

Front

What is the formula to calculate Voltage in a circuit?

Back

Voltage (V) = Current (I) × Resistance (R)

What is the Voltage of a circuit with a resistance of 5 Ω and a current of 2 A?

Back

10 V

Front

What characterizes a series circuit?

Back

The same current flows through all components.

Front

What happens to a series circuit if one light bulb is unscrewed?

Back

The circuit will not work.

Front

Why are electrical cords covered in plastic or rubber?

Back

Because plastic and rubber are insulators which keeps us safe.

Front

What is an insulator?

Back

A material that does not allow electricity to flow through it easily.
