Discribe ohm's Law?
Answers
Explanation:
Ohm's law states that the current through a conductor between two points is directly proportional to the voltage across the two points. Introducing the constant of proportionality, the resistance, one arrives at the usual mathematical equation that describes this relationship: I=V/R, where I is the current through the conductor in units of amperes, V is the voltage measured across the conductor in units of volts, and R is the resistance of the conductor in units of ohms.
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)
