Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

An AC circuit operates at a frequency of 50 Hz. Calculate the period, and determine the inductive reactance for a 2 H inductor.

💡 Hint: Use f = 1/T and XL = 2πfL formulas.

Challenge 2 Hard

A 50 μF capacitor and a 10 mH inductor are in a circuit. Calculate their reactances at 60 Hz and explain which will dominate.

💡 Hint: Compare XL and XC to see which one is larger.
