What is a resistor?

It is a device that provides a certain resistance value. In electronics, it is used to limit the current flow.

Why use a resistor?

It has several benefits. It allows you to adjust the current flow, so you can protect your circuit from damage. It allows you to use a voltage source, and a voltage divider to create a more stable power source. It can be used to make a more stable power source for a circuit, and it can also be used to limit the current flow.

How to calculate the resistance value?

The calculation of the resistance value is not that difficult.
