Question

To measure the resistance and impedance of an inductor with or without iron core

Answer 1

Below are given the methods for measuring the impedance and inductor with and without iron core.

Explanation:

Without iron Core:

• To measure the impedance and resistance of an inductor an circuit is made.
• The variable out put source of the circuit is connected to A.C mains A.C ammeter and A.C voltmeter for measuring A.C current and voltage.
• The circuit will obey ohm's law.

With iron core:

• Insert the iron core inside the hollow core of the inductor and then connect it to the A.C mains, A.C ammeter and A.C voltmeter for measuring current and voltage.
