mAh full form and mAh meaning in battery capacity calculation

mAh full form is milli Ampere hour, which means how much amperes of current a battery can deliver in an hour time. The battery mAh capacity rating refers to the storage capacity available for a particular battery especially for rechargeable batteries. For example battery with a capacity rating of 1800 mAh could deliver a current… Read More »

What is Corona Effect in Electrical Transmission Lines

The phenomenon of ionization of surrounding air around the conductor, hissing noise and production of Ozone gas in an overhead transmission line is known as Corona Effect. Corona discharge is a process by which a current flows in a conductor with a high potential into a neutral fluid, usually air, by ionizing that fluid so… Read More »

Star or WYE (Y) Connection

In this method of inter-connection the similar ends either the ‘start’ or ‘finish’ are joined together at point N. This common point N is called star point or neutral point. Ordinarily only three wires are carried to the external circuit giving 3-phase, 3-wire star connected system but sometimes a fourth-wire, known as neutral wire is… Read More »

Resistance vs Conductance

The opposition to flow of electrons (due to bonds between protons and electrons, as well as to collisions) is called a electrical resistance (R). Or Resistance may also be defined as “The property of the electric circuit which opposes the flow of current”. The practical unit of electric resistance is ohm (.Q). It (ohm) is… Read More »

Wiring Installation for lighting & Power Points

Electrical wiring generally refers to insulated conductor used to carry current including the associated devices. Domestic electric appliances like lights, fans, washing machines, water pumps etc are connected to the supply through insulated wires which are controlled by switches. The wiring diagram gives the connections of different appliances to the supply within a house or… Read More »
