Resistor
It is one of the most critical components of PCBs. It is used to control voltage and the current flowing through a circuit.
We use a resistor to control the voltages and the winds in a course. If connected in series with a load, it can control the current flowing through the circuit and reduce the chances of the bag burning out.

Capacitor
The component is mainly used to stabilize the voltage supplied to a circuit. It behaves like a battery that can store charges and introduce some time delay in the course.
Capacitors can be divided into polarized and non-polarized capacitors.

Light Emitting Diode (LED)
It is a component that gives light and can give visual feedback from a circuit. It can be used to make fantastic light show circuits. Diodes allow current to flow in one direction.

Transistors
It acts like a switch that is controlled by an electrical signal. Transistors can be used in amplifiers since they amplify charges.

Inductor
It is a coil of wire that is used as a filter.
The work of an inductor is to stop the change of current and store charges.

An integrated circuit
It consists of an electrical circuit that has been shrunk to fit on a chip. It could be an amplifier, a microprocessor, or a USB to a serial converter.
