A current of 10 Ampere flows through a wire whose ends are at a potential difference of 3 Volts. Calculate the resistance of the wire.

Correct option is C

The correct answer is (c) 0.3 Ω.
· Using Ohm's Law: R== Ω
The resistance of the wire is 0.3 Ω. ​
Information Booster:
· Ohm’s Law: States that the current through a conductor between two points is directly proportional to the voltage across the two points when temperature remains constant.
· Resistance Units: Resistance is measured in ohms (Ω).
· Practical Application: Calculating resistance helps in designing circuits to ensure proper functioning and safety.
