Challenge Circuit 3

real inductor Circuit

As we understand, inductors are made with conductors, which have small resistance. So a real inductor will always have a resistive and an inductive component. 

Try solving the Real Inductor Circuit question below and share it with your students.


  • The inductor we are using here is 18 ohms, 92mH
  • Supply is 15V AC 50Hz

Calculate the expected values in the circuit when the toggle switch is flipped and the circuit is energised.
