Answer:
Explanation:
Question :-
State the physical quantity which is equal to the ratio of potential difference and current. Define its SI unit.
Answer :-
Electrical Resistance, R = V/I
The Resistance of a conductor is said to be one ohm (Ω) if the potential difference applied across its ends is 1 volt and the current of 1 A flows through it. It SI unit is ohm (Ω).
1 ohm = 1 volt/1 ampere.
Extra Information :-
One Volt Potential Difference - The potential difference between two points in an electric field is the amount of work done in bringing a unit positive charge from one point to another.
Potential Difference = Work done/Charge = W/Q
