Electricity and Magnetism

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 incomplete circuit?

Back

A circuit that does not have a complete path for current to flow.

Front

What happens in a series circuit if one of the light bulbs is unscrewed?

Back

The circuit will not work.

Front

What is part C considered in the circuit?

Back

Load/Resistor.

Front

How do you calculate current in a circuit?

Back

Current (I) = Voltage (V) / Resistance (R).

Front

What is the unit of electrical resistance?

Back

Ohm (Ω).

Front

What is the function of a power source in a circuit?

Back

To provide the voltage needed to push current through the circuit.

Front

What is a conductor?

Back

A material that allows electricity to flow through it easily.

Front

What is an insulator?

Back

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

Front

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

Back

Ohm's Law: V = I × R.
