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 difference between a series circuit and a parallel circuit?

Back

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

Front

What is a conductor?

Back

A conductor is a material that allows electricity to flow through it easily, such as copper or aluminum.

Front

What is an insulator?

Back

An insulator is a material that does not allow electricity to flow through it easily, such as rubber or glass.

Front

What is a switch in a circuit?

Back

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

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 voltage?

Back

Voltage is the electrical potential difference between two points in a circuit, measured in volts.

Front

What is current?

Back

Current is the flow of electric charge in a circuit, measured in amperes (amps).

Front

What is resistance?

Back

Resistance is the opposition to the flow of electric current, measured in ohms.

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 can be expressed as V = I × R.
