what is a resistor

Resistor is an electrical component that reduces the electric current.

The resistor's ability to reduce the current is called resistance and is measured in units of ohms

why do we use them

the relationship between voltage, current, and resistance in any circuit is so regular, we can reliably control any variable in a circuit simply by controlling the other two.While there are differences in how a resistor affects the two different types of current sources depending on how the resistor is constructed and the AC frequency involved,
