OHM'S LAW

Before you will be qualified to an electrical engineer you must knw the meaning and every aspect of ohm's law.....
OHM'S LAW=state that the current through a conductor between two points is directly proportion to the Potential Difference (P•D) across the two point.
Introducing the constant of proportionality ,the resistance,one arrives at the mathematical equation that discribes this relationship..
[I=V/R]
Where I is the current through the conductor in units of Amperes. {V} is the P•D measure across the conductor in unit of Volt
{R} is the resistance of the conductor in unit of OHMS.
