 Ohm's law (George Simon Ohm)

 There are 3 main quantities in electrical i.e   Voltage, Current & Resistance.

 Ohm's law formula used to   calculate relationship between voltage,   current & resistance in an electrical   circuit (V=I×R).

 

 

 Ohm's law states that:- The current   flowing to   the linear conductor is directly   proportional to   potential difference   between two ends of the conductor when   temperature remain constant.

 

 Statment 2:- The current flowing through   a conductor is directly proportional to the   voltage & inversely proportional to the   resistance.

 

 Meaning Of V=I×R:- Electrical current is   directly proportional to the voltage &   inversely proportional to the resistance.

                         V↑ I↑ & R↑ I↓

 Derivation for Ohm's Law:- 

                            R∝L

                            R∝1/A

                            R∝L/A

                            R=⍴L/A

 

 Formulas for Ohm's Law:-

        

            V=I×R,    I=V/R,    R=V/I
