Types of Electrical Load — Inductive & Resistive Load

Inductive vs. Resistive Loads（感性负载 vs. 阻性负载）

Electrical circuits include a power source, a load, and a switch to connect/disconnect the source and load.
Different devices service different functions; different functions require different types of electrical loads.

Inductive Loads（感性负载）

(Devices with moving parts, like a fan or washing machine)
Functions by using a coil or windings to produce a magnetic field.
When voltage is applied, the load resists changes in current flow.
This means the current lags behind the voltage.

Resistive Loads（阻性负载）

(Devices that produce heat, like a lightbulb or kitchen oven)
Functions without using a magnetic field, purely heat.
The current peaks at the same time as the voltage and the waveforms are in-phase.
No voltage spike is created when switched off.
