Questions & Step-by-Step Solutions
If the voltage across an inductor is 12V and the current is 2A, what is the inductive reactance? (2023)
Step 1: Identify the voltage across the inductor, which is given as 12V.
Step 2: Identify the current flowing through the inductor, which is given as 2A.
Step 3: Use the formula for inductive reactance, which is XL = V/I.
Step 4: Substitute the values into the formula: XL = 12V / 2A.
Step 5: Perform the division: 12 divided by 2 equals 6.
Step 6: Conclude that the inductive reactance XL is 6Ω.
Inductive Reactance – Inductive reactance (XL) 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 flowing through it.
