What is a Fuse?

Back

A fuse is a safety device used in electrical circuits to prevent too much electricity from flowing, which can cause overheating and fires.

What is Voltage?

Back

Voltage is the measure of potential energy stored in a battery, indicating how much energy is available to push electric charges through a circuit.

Front

What is a Parallel Circuit?

Back

A parallel circuit is a type of electrical circuit where each component has its own separate path for the current to flow, allowing multiple devices to operate independently.

Front

What is a Closed Circuit?

Back

A closed circuit is a complete electrical loop that allows current to flow. It requires a power source, conductive path, and a load.

Front

What is a Transistor?

Back

A transistor is a semiconductor device used to amplify or switch electronic signals and electrical power in circuits.

What is Resistance?

Back

Resistance is a measure of how much a material opposes the flow of electric current, affecting how much current can flow through a circuit.

Front

What is a Potentiometer?

Back

A potentiometer is a variable resistor that can be adjusted to change the resistance in a circuit, often used to control voltage.

Front

What is an LED?

Back

An LED (Light Emitting Diode) is a semiconductor device that emits light when an electric current passes through it.

What is the function of a Battery?

Back

A battery stores chemical energy and converts it into electrical energy to power devices.
