Ohm's Law: "In a DC circuit, the Current (I), is Directly Proportional to the Voltage (V) and Inversely Proportional to the Resistance (R), at Constant Temperature".
I = V/R = Amps.
V = I x R = Volts.
R = V/I = Ohms.
Ohm's law applies to electrical circuits; it states that the current through a conductor between two points is directly proportional to the potential difference (i.e. voltage drop or voltage) across the two points, and inversely proportional to the resistance between them.
Ohms law can be applied to to both electrical and magnetic circuits also.
in eletrical network:-
emf induced = current X resistance
this explains the basic electrical principle.
here in electical network ,currents flow ....... resistance of material opposes it.
in magnetic network:-
mmf induced = flux X reluctance
here in magnetic network , flux flow ....... reluctance of material opposes it.
