Short circuits and overloads are abnormal conditions that cause heavy current flow in a circuit. Heavy currents are capable of damaging a device or a circuit and may end up…
Overhead transmission lines are not insulated primarily due to three reasons: first and foremost is to reduce the weight of the lines, secondly to save cost and the last is…
Circuit protection devices such as fuses and MCBs are used to safeguard any equipment from damages caused due to short circuits. The usage of these devices does not mitigate the…
The utilization categories AC-1 and AC-3 defines making, breaking and continuous operation current rating for contactors. Based on these rating, contactor for switching of resistive loads and switching of squirrel…
It is necessary to select the correct rating of switchgear for any application. Therefore, during selection, it is necessary to know the characteristics of the load. The International electrotechnical commission…
Air conditioners are one of the major power-consuming loads at home. This calculator can help you calculate electricity usage of your air conditioner and the usage cost. How to use…
Thevenin's and Norton's theorems are circuit simplification methods, applied to simplify complex linear circuits and making circuit analysis easy and fast. These theorems are proposed by Léon Charles Thévenin and…
A few small behavioural changes and other adjustments can help us save electricity as well as electricity bills. By saving electricity we are not only saving money but also saving…
In an electric circuit, power flows from the source to the load. The source itself has some amount of impedance which affects the current flow. Therefore, transfer of power depends…
Its hot inside lets turn on the AC!! The air conditioner is one of the high power consuming appliances at home. During sunny days you might have noticed a drastic…
