Transformer Polarity Test – Additive, Subtractive and Transformation Ratio Test
Transformer Polarity Test Transformer Polarity is the relative direction of the induced voltages between the high voltage terminals and the low voltage terminals. The winding terminals of a transformer possess polarities. The polarity test...
Why Fuse is not connected in Neutral ?
In electrical circuits, fuses are used as a protective device to prevent the circuit from an excess current flow. An excess current flow can cause due to many reasons such as short circuit, overload, etc....
Difference Between Fuse and MCB (Miniature Circuit Breaker)
The MCB and a normal fuse have the same function. Both, are used to prevent the circuit from an excess flow of current resulted due to short circuit or overload. When the current flow...
Why do we Need a starter in DC motors?
While starting a DC motor huge amount of current can be driven to the windings due to the absence of the back emf. The current may rise about 4-6 times higher than the rated load current...
Inductive reactance formula derivation and calculation
Inductive reactance equation derivation Inductive reactance (XL) is a measure of the opposition to current flow in an inductive circuit. It is caused by the magnetic field that is generated around the conductor when...
Capacitive reactance formula derivation and calculation
Capacitive reactance equation derivation Capacitive reactance (Xc) is a measure of the opposition to current flow in a capacitive circuit. It is caused by the electric field that is generated between the plates of...
Why earth pin is thicker and longer?
