hand, a wire wound transformer is an inductive load and the current tends to lag behind the voltage. Once triggered a triac or thyristor relies on the current flowing through the device to keep it conducting. Should the current fall below the device’s threshold level it will turn off and stop conducting. However with an inductive

Why most reactive loads are inductive - Answers

Typical resistive loads are heating elements in water heaters, etc. A 'reactive' load is one which results in a load current that either lags (inductive) or leads (capacitive) the supply voltage.

Induction as a heat source for steam? - Heating Help: The Wall

Even if NG plants burn with greater efficiency than your average boiler, electrical distribution losses probably wash out that benefit. Inductive heating can never be more efficient than a resistive heating element immersed in the water. That is basically 100% efficient.

There are many ways to treat water, and different treatments have different goals. Often the goal is demineralization, which is the removal of all or nearly all of the contaminants. In

Resistive heating explained in details - EEP

In fact, resistance and current are inversely proportional in this case: if one doubles, the other is halved. What, then, is the effect of resistance on power consumption? The key here is that resistive heating depends on the square of the current, meaning that the power is more sensitive to changes in current than resistance.

Basic Operating Principle of an Inductive Proximity Sensor

Basic Operating Principle of an Inductive Proximity Sensor. This creates a small amount of power loss in the form of heat (just like a little electric heater). The power loss is not entirely replaced by the sensor’s internal energy source, so the amplitude (the level or intensity) of the sensor’s oscillation decreases.

Energy - Engineering Energy Center

The efficiency of the boiler is a measurable value presented as the ratio between the energy that was produced by the boiler and the energy that the boiler used for combustion of fuel. Maintaining the efficiency of the steam boiler can be achieved by keeping the combustion process under constant control , by cleanness of the heating surfaces and by the good insulation of the boiler .

Inductance, capacitance and resistance

• Since resistance doesn’t effect phase the net of the two reactances, with the lessor subtracted from the greater, will act upon total impedance at 90° to resistance. • But since reactance is already expressed in the form of Ohms in a purely reactive circuit Ohms laws applies normally for a purely inductive or capacitive circuit.


• The heating and cooling plant - furnace, boiler or heat pump, and possibly air conditioner - that converts fuel or electrical energy into a temperature change. • The distribution system - ducts for forced air or pipes for hot water or steam - that carries heat (and cool) from the central unit to each room in the house.

Electric heating - Wikipedia

Methods of electric heating include resistance heating, electric arc heating, induction heating, and dielectric heating. In some processes (for example, arc welding), electric current is directly applied to the workpiece. In other processes, heat is produced within the workpiece by induction or dielectric losses. As well, heat can be produced then transferred to the work by conduction, convection or radiation.

what is inductive reactance? | Yahoo Answers

Nov 19, 2007 · Answers. Inductance is normally associated with circuit elements called coils and a coil`s inductance value is measured in units called henrys. Inductive reactance in a coil is directly proportional to the inductance value in Henrys and also directly proportional to the frequency of the applied ac voltage.

A pilot-scale laboratory experience for an inductive learning

During the boiler operation, once the system start-up is over, students can observe the operating batch mode of the boiler (video V0); first, the steam pressure increases from 2.5 to 7.5 bars, then the boiler stops, the steam pressure decreases to 2.5 bars, and a new cycle begins. Students realize that when the steam pressure is increasing, there is a fluid flow-rate in the five streams associated with the boiler.


AC waveforms are usually sinusoids. Loads are of three types. Resistive, inductive, capacitive. When the load is resisitive, the voltage and the current waveforms are in phase with each other. If it is inductive, current lags the voltage and if it is capacitive, current leads the voltage.

Difference between inductive and capacitive? | Yahoo Answers

Nov 24, 2011 · Answers. This would imply the impedance is inductive. If the impedance's phase angle is negative, that means the impedance is rotated away from pure resistive (positive real) toward a negative imaginary component. This would imply the impedance is capacitative. This particular example component has a negative phase angle,
