The electricity which we use at home is normally the alternating current or AC. AC current is result of alternation of the generator armature or alternator. The electricity or current flows in one direction and then reverse direction. Each cycle in AC current consists of a positive and a negative alternation. During AC generation waveform produced… Read More: Understanding Alternating Current or AC Current »
Ampere’s circuital law states that the line integral of magnetic field intensity about any closed path is exactly equal to the direct current enclosed by that path. In the figure below, the integral of H about closed paths a and b gives the total current I, while the integral over path c gives only that… Read More: Ampere’s Circuital Law [Explained] »
As a new electrical student or a common man this questions comes in mind that why we prefer 3 phase power system. In recent years 3 phase electric wiring has become common and mostly used worldwide for power generation, power transmission, distribution and three phase engines or motors. A single-phase electric power supply is the… Read More: Single phase and 3 phase power comparison »
A stepper motor is an electromechanical device which converts electrical pulses into discrete mechanical movements. The shaft or spindle of a stepper motor rotates in discrete step increments when electrical command pulses are applied to it in the proper sequence. Stepper motor (or step motor) is in fact a brushless DC electric motor that divides… Read More: Stepper Motor Principle Types and Applications »
A voltage regulator is used to regulate or stabilize the voltage level for specific purpose. Voltage fluctuations are never acceptable for any appliance or equipment, because it may damage the electrical appliances etc. When a steady, reliable voltage is needed, then voltage regulator is the preferred device. Despite varying inputs or load conditions a stabilizer… Read More: Voltage Regulator and Stabilizer – Simple Explanation »
In power generation the calorific value of fuel is prime factor. Use of fuels having high heat of combustion gives best output in terms of cost of electricity or energy generated. When we generate electricity in steam power plant we have to burn fuel like coal, petroleum oil or flammable gases. In thermal powers generation… Read More: Calorific Value of Diesel Petrol & Coal – Fuels Heat… »
