Safety is the primary element of any circuit or electrical connection. Whether it is electric iron or refrigerator or any other home appliances, everywhere safety has to be ensured to…
This article focus on explaining the similarities and dissimilarities between neutral and Earth (ground). Understanding the difference between the neutral and earth may be difficult in the beginning. A Lot…
Over-current Any situation in which the current flow through a device or conductor exceeds the desired value is known as over current. Both overload and short circuit can cause excessive…
Short Circuit A short circuit occurs when two or more current carrying conductors of different phases or different voltage levels or different terminal (in DC circuits) come in contact with…
Ammeter is a device used to measure the current flow through a conductor. The name is derived from the unit of current, Ampere. Ammeter is either connected in series to…
Isolator or disconnectors, as the name indicates, is a switching or isolation device, intended to disconnect an equipment or electrical Circuit from the supply. It is an offload device, which means it can be operated only when the current passing through it is zero. Unlike circuit breakers, it lacks a built-in arc suppression system. It can be operated only during offload conditions. (more…)
Transformer action is a phenomenon by which EMF(Electro-motive force) is induced in from one coil to the other coil by electro magnetic induction. It is the basic principle of electric transformers.
MCB (Miniature circuit breaker) is a resettable device designed to protect a circuit from short circuits and overcurrents. Trip curves of MCB's (B, C, D, K and Z curves) tell…
Stalling is a condition at which a motor stops rotating even when there is sufficient voltage at it’s terminals. This condition occurs when the torque required by the load is more than the maximum torque (Breakdown torque) that can be generated by the motor. At this condition, the motor drains the maximum current and the speed comes zero.
