The Circuit

Front

What is a circuit?

Back

A circuit is a closed loop that allows electricity to flow through it, consisting of a power source, conductors, and a load.

Front

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

Back

The power source provides the electrical energy needed to drive the current through the circuit.

Front

What are conductors?

Back

Conductors are materials that allow electricity to flow through them easily, such as copper and aluminum.

Front

What is a load in a circuit?

Back

A load is any device that uses electrical energy to perform work, such as a light bulb or a motor.

Front

What is the difference between series and parallel circuits?

Back

In a series circuit, components are connected end-to-end, so the current flows through each component one after another. In a parallel circuit, components are connected across common points, allowing current to flow through multiple paths.

Front

What happens if one component fails in a series circuit?

Back

If one component fails in a series circuit, the entire circuit is broken and all components stop working.

Front

What happens if one component fails in a parallel circuit?

Back

If one component fails in a parallel circuit, the other components can still function because they have separate paths for current.

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) of the conductor, expressed as V = I × R.

Front

What is resistance in a circuit?

Back

Resistance is a measure of the opposition to the flow of electric current, measured in ohms (Ω).

Front

What is a switch in a circuit?

Back

A switch is a device that can open or close a circuit, allowing or stopping the flow of electricity.
