Electric Circuits

Front

What type of circuit is required for a light bulb to be ON?

Back

A closed circuit.

Front

Define a conductor in the context of electric circuits.

Back

A conductor is a material that allows electricity to flow through it, completing the circuit.

Front

What is the form of energy that can produce light, heat, motion, and magnetic force?

Back

Electricity.

Front

What is an electrical circuit?

Back

An electrical circuit is a complete, unbroken path through which electric charges flow.

Front

If the electric circuit is CLOSED, what state is the switch in?

Back

The switch is ON.

Front

What is an open circuit?

Back

An open circuit is a broken path that prevents electric charges from flowing.

Front

What role do resistors play in an electric circuit?

Back

Resistors limit the flow of electric current in a circuit.

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 happens to the total resistance in a series circuit when more resistors are added?

Back

The total resistance increases.

Front

What is Ohm's Law?

Back

Ohm's Law states that the current (I) through a conductor between two points is directly proportional to the voltage (V) across the two points and inversely proportional to the resistance (R). It is expressed as V = IR.
