Question: If the voltage across an inductor is 100 V and the current through it is 2 A, what is the inductive reactance? (2023)

Options:

  1. 50 Ω
  2. 200 Ω
  3. 100 Ω
  4. 25 Ω

Correct Answer: 50 Ω

Exam Year: 2023

Solution: 

Inductive reactance (X_L) is given by X_L = V/I. Here, X_L = 100 V / 2 A = 50 Ω.

Questions & Step-by-Step Solutions

If the voltage across an inductor is 100 V and the current through it is 2 A, what is the inductive reactance? (2023)
  • Step 1: Identify the voltage across the inductor. In this case, it is 100 V.
  • Step 2: Identify the current through the inductor. In this case, it is 2 A.
  • Step 3: Use the formula for inductive reactance, which is X_L = V / I.
  • Step 4: Substitute the values into the formula: X_L = 100 V / 2 A.
  • Step 5: Calculate the result: X_L = 50 Ω.
  • Inductive Reactance – Inductive reactance (X_L) is the opposition that an inductor offers to the flow of alternating current (AC) due to its inductance, calculated as the ratio of voltage across the inductor to the current through it.
