WHAT IS OHM'S LAW......???
Answers
Answer:
Ohm's Law is a formula used to calculate the relationship between voltage, current and resistance in an electrical circuit. To students of electronics, Ohm's Law (E = IR) is as fundamentally important as Einstein's Relativity equation (E = mc2) is to physicists. E = I x R.
According to Ohm's law,
Current flowing in a conductor is directly proportional to the potential difference applied across to its ends at constant temperature & physical conditions.
So, According to the definition
V ∝ I
V/I = constant
Put the constant as “r” which indicates the resistance of the conductor.
R = V/I
V = IR
Where
I = current flowing in the conductor
V = potential difference applied across the conductor
R = resistance of the conductor
Unit of Resistance is called omega (Ω)
