Components of a circuit

1. Basic components: It consists of a battery, push button, resistor, LED and capacitor.

2. Circuit Assembly: Circuit assemblies are simple, pre-made circuits that can be incorporated into 3D designs.

3. Rotate: It is used to rotate any component placed onto the workspace.

4. Start/Stop Simulation: Start/Stop Simulation tests the working of circuits and components.

§ A breadboard is a piece of plastic that has several holes. These holes are used to hold different electronic components.

§ A Light Emitting Diode (LED) is an electronic device that emits light when an electric current passes through it.

§ The voltage(v) indicates the pressure from the electronic circuit power source.

§ A resistor is used to restrict the flow of current to electrical components. Electrical current is measured in ‘Amps’.
