Question

what is OHM's law ?Express it mathematically? Also write the unit of resistance and define it.

Answer 1

The current passing through a conductor is directly proportional to the potential difference across two points...V is proportional to IR
The unit of resistance is metre...and is defined as 1ampere of current passing through 1ohm resistance...hope it helps.....make me a brainliest plz...

Answer 2

what is OHM's law ?Express it mathematically? Also write the unit of resistance and define it.

$\huge\mathbb\blue{Answer:-}$

=>The law that for any circuit the electric current is directly proportional to the voltage and is inversely proportional to the resistance.

=>Mathematically , Ohm's law is given by

I∝V

I= V/R

V=IR

Where v is the potential difference , I is the current and R is the resistance

=>Electrical resistance of a conductor may be considered as a measure of the opposition offered by it for the flow of electric charge through it.

SI unit of resistance is ohm.
