Working Principles and Identification of Resistive Load and Inductive Load Appliances

Published: December 2, 2025

In modern household power supply systems, household appliances can be primarily categorized into two major types based on how they convert electrical energy into other forms of energy: resistive loads and inductive loads. Understanding the fundamental differences between these two types is crucial for selecting the right protection devices.

Resistive Loads (e.g., heaters, incandescent bulbs) convert electrical energy directly into heat. They have a power factor close to 1 and draw current in phase with voltage. These devices are generally easier to protect.

Inductive Loads (e.g., motors, compressors in fridges and ACs) store energy in magnetic fields. They have lagging current, lower power factor, and generate back EMF during switching—requiring more sophisticated surge and voltage protection.
