Electric Circuits

Front

What happens if a circuit is OPEN?

Back

The circuit is broken and the light will NOT work.

Front

What are the three components needed for a complete circuit?

Back

Wire, load, and energy source.

Front

Is a paperclip an insulator or a conductor?

Back

Conductor.

Front

What is the primary energy transformation in an electric heater?

Back

Electrical energy is transformed to heat.

Front

How does a speaker convert electrical energy?

Back

Electrical energy is converted to sound.

Front

What is a closed circuit?

Back

A closed circuit is a complete electrical loop that allows current to flow.

Front

What is the role of a resistor in a circuit?

Back

A resistor limits the flow of electric current.

Front

What is the difference between series and parallel circuits?

Back

In a series circuit, components are connected end-to-end, while in a parallel circuit, components are connected across common points.

Front

What is Ohm's Law?

Back

Ohm's Law states that the current through a conductor between two points is directly proportional to the voltage across the two points.

Front

What is the unit of electrical resistance?

Back

Ohm (Ω).
