OHM's Law

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.
