A low power factor is the result of inductive loads such as transformers and electric motors. Unlike resistance loads creating heat by consuming kilowatts, inductive loads require a current flow to create magnetic fields to produce the desired work.

## Are Motors inductive loads?

Reactive/Inductive Load – An inductive load converts current into a magnetic field. Inductive reactance resists the change to current, causing the circuit current to lag voltage. Examples of devices producing reactive/inductive loads include motors, transformers and chokes.

## Is a motor a resistive or inductive load?

As you might guess from the name, resistive loads only resist the current and are the simplest type of load. In inductive loads, such as an electric motor, the voltage wave is ahead of the current wave.

## Is refrigerator an inductive load?

Loads that power electrical motors are inductive loads. These are found in a variety of household items and devices with moving parts, including fans, vacuum cleaners, dishwashers, washing machines and the compressors in refrigerators and air conditioners.

## What is a non inductive load?

The load is connected to an electric circuit and it consumes electric energy. Loads are divided into inductive loads and non-inductive loads. An inductive load contains a coil, such as a motor. Non-inductive loads are divided into lamp loads and resistive loads.

## What are examples of inductive loads?

Any devices or equipment that have coils in them are inductive in nature. Examples of inductive load are motors, solenoids, contactor coils, compressors, speakers, relays, transformers, inductors, power generators, etc.

## Are LED lights inductive loads?

LEDs are a nonlinear load and probably these lamps will not have a power factor correction converter. This means that the current will not be sinusoidal therefore you will have some reactive power flowing. There may be a PFC choke before the rectifier bridge.

## Are LED lights inductive or resistive load?

“When migrating from incandescent bulbs to either CFLs or LED lighting, the load isn’t resistive anymore, it’s inductive or capacitive so the dimmer doesn’t behave the same way as it would with an incandescent bulb.” “The result is flickering when the dimmer interacts with the input of the LED drivers,” Anumula added.

## How do you know if a load is inductive or capacitive?

If both inductors and capacitors are present then simply find the equivalent impedance of the load network. If the imaginary part of the equivalent impedance is positive then the load is inductive, if it is negative then it is capacitive, and if it is zero then it is resistive.

## How do you calculate inductive load?

The formula for calculating the inductive reactance of a coil is: inductive reactance, or XL, is the product of 2 times p (pi), or 6.28, the frequency of the ac current, in hertz, and the inductance of the coil, in henries. XL =2p x f x L.

## What type of load is a heater?

Two common examples of resistive loads are incandescent lamps and electric heaters. Resistive loads consume electrical power in such a manner that the current wave remains in phase with the voltage wave. That means, power factor for a resistive load is unity.

## What type of load is a refrigerator?

Typically, a REACTIVE load contains an electric motor. This type of load may require up to three times as much power (wattage) to START as it does to keep it running. Examples of REACTIVE type loads are air conditioners, refrigerators / freezers, furnace fans, well pumps, bench grinders and air compressors.

## Is a microwave an inductive load?

By convention, a “lagging” or inductive load, such as a motor, … A “leading”, or capacitive load, such as a microwave oven, has negative reactive power.

## What is the difference between inductive and non inductive resistors?

A non-inductive resistor is wound one way then again in the other direction, as shown below. … A non-inductive resistor can be used to replace an inductive resistor, but that might not be a realistic goal. Inductive resistors are typically cheaper to construct and are more commonly made with higher power ratings.

## What are examples of capacitive loads?

Examples of capacitive loads are capacitors, variable or fixed capacitor banks, motor starting capacitors, generators, and synchronous motors. Inductive and capacitive loads are opposite in nature. Equal amounts of inductive and capacitive loads within the same system will offset each other leaving only real power.

## Is a battery considered a load?

An electrical load is an electrical component or portion of a circuit that consumes (active) electric power. This is opposed to a power source, such as a battery or generator, which produces power. In electric power circuits examples of loads are appliances and lights.
