Question

A conductor is said to have resistance of one ohm if a potential difference of one volt across its terminals causes a current of X ampere to flow through it. What will be the value of X? (a) 4 (b) 2 (c) 3 (d) 1 I had been asked this question in my homework.

Answer 1

Correct option is (d) 1 The best explanation: Ohm’s law states that the potential difference (voltage) across a conductor is proportional to the current through it. The constant of proportionality is called the Resistance(R). According to Ohm’s law, V = IR (where V is the potential difference between two points which include a resistance R). –> I = V/R = 1V/1Ω = 1A.
