Question

State the physical quantity which is equal to the ratio of potential difference and current. Define its SI unit.

Answer 1

The physical quantity which is equal to the ratio of potential difference, i.e. voltage and current is resistance. The standardized (SI) Unit of resistance is Ohms. Ohm is the name of a scientist. Being an Electronics and Physics student, you might be knowing the Ohm's Laws.

Answer 2

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
