Is a coil resistive or inductive?

Is a coil resistive or inductive?

Now in an AC circuit, the opposition to current flow through the coils windings not only depends upon the inductance of the coil but also the frequency of the AC waveform. In other words, an inductors electrical resistance when used in an AC circuit is called Inductive Reactance.

What is considered a resistive load?

Resistive Load Resistive Loads is any electrical device that consisting of heating element, and working based on the Resistances Working principle. Resistive loads only consumes Active Power, and does not cause changes in the value of the power factor, so the value of the power factor remains, which is equal to one.

Are LED lights resistive or inductive?

LED are semiconductors that are are resistive and slightly capacitive at the junction. They produce light when a forward DC voltage is applied to them. The Driver that create the DC voltage is a no linear load. The drivers are essentially electronic DC switching power supplies.

Are LED drivers inductive?

LED drivers are by inherent nature either capacitive or Inductive. Many low cost bulbs in lower wattages use Ac capacitor 0.22 Mf or 0.4 mf to Just drop the Ac voltage to lower voltage , then add full wave rectifier to drive the LEDs in non- isolated mode.

How is an inductive load different from a resistive load?

Inductive loads require magnetic field to operate. So, appliances and gadgets made of coils are inductive in nature. Inductive loads take time to develop there magnetic field when the voltage is applied, so the current is delayed As the current lags the voltage the inductive load is present.

What happens when you turn off an inductive load?

When you turn off the power, the current quickly drops to zero and no damage is done. Inductive loads are another matter. If you’re using a DC power supply to power DC motors, solenoids, fans, relays and other inductive loads, you need some kind of circuit protection.

Can a resistive load damage a DC power supply?

Resistive loads are easy on a DC power supply. When you turn off the power, the current quickly drops to zero and no damage is done. Inductive loads are another matter. If you’re using a DC power supply to power DC motors, solenoids, fans, relays and other inductive loads, you need some kind of circuit protection.

How is an inductive load connected to a DC power supply?

Figure 1 shows an inductive load connected to a DC power supply. When the power supply is turned on, current flows through the coil and a magnetic field builds up around the inductor. That magnetic field is a source of potential energy.
