Ohm's law

A resistor resists the flow of charge. when a voltage source is connected to a circuit, the voltage will couse a uniform flow of electrons through that circuit called a current.

when a voltage V is applied to a resistor, some current flow through the resistor, and the current is found by using this equation

V

I= ------

R

R is the value of the resistance. It is measured in units of Ohms. and is shown this symbol **Ω.**
