How to calculate how much will be the electricity bills for your operating electric heater?

E lectricity bill have to be paid for the energy you have utilized in the form of electricity. Electricity company bill you for your energy consumption in kwh. A kwh energy is said to be consumed, if a 1kw consuming device or appratus is stayed turned ON for one hour. This is the simplest definition you can find at various other website too. But there is a something you have to bother about. The electricity bill, for instance a 1HP(745W) motor, can be higher than what the device is consuming. The reason is that often devices or apparatus, like motor, have capacitance and inductance associated with them. Because of these, inductance and capacitance, the power factor is less than one. which results in extra loads to the transmission system and hence, electricity company charges for these unnecessary load. Don't worry if you so not understand power factor at this point of time.In very simple form, remember, the more the power factor, lower will be the reactive power consumtion(A power

How an Induction Heater Works?

    A n induction heater, as the name suggest works on the principle of induction. Here by the term Induction means to induce, induce an electric current. This induce electric current is also called eddy currents. In these type of heater, the principle of heating is same, the resistance heat produce due to resistance of the material to the flow of electric current. But in this system, we are not providing an external Voltage potential source, which, in conventional electric heating provide the required potential for the electrons to flow, Instead we are making the electrons to flow in to fro direction because of rapidly changing polarity. The change in Polarity is made by electromagnetic radiation that impinges to the surface of the material to be heated by a suitable formed emitter, usually formed  as a coil. Based on the frequency, the polarity changes form +ve to -ve and again form -ve  to again +ve a number of times in a given time. Because of this changing potential, a changing
