Ohm's law describes the mathematical relationship among?
Answers
V= IR
Where V is voltage and I is current
Then R is resistance.
Voltage (V) described as product of current and resistance.

Explanation:
Ohm's law .
→ Ohm's law gives a relationship between current and potential difference .
→ According to Ohm's law : At constant temperature , the current flowing through a conductor is directly proportional to the potential difference across its end .
→ If I is the current flowing through a conductor and V is the potential difference ( or voltage ) across its ends , then according to Ohm's law :
I∝V ( At constant temperature ) .
This can also be written as : V∝I
Or V = R × I .
Where R is a constant called “resistance” of the conductor .
★ Resistance of a conductor : The property of a conductor due to which it opposes the flow of current through it is called resistance .
→ The resistance of a conductor depends on length, thickness, nature of material and temperature of the conductor.
→ The SI unit of resistance is ohm( Ω ) .
