How to calculate short circuit current for transformer

Short circuit current for transformer: Generally we know short circuit current is nothing but low impedance path having abnormal contacts between two points of different  potentials. so short circuit calculation is very important to protect the equipment and people from high mechanical force and high heat stress. so we need to calculate the short circuit…

Why we are using carbon brush in motor

Carbon brush: why we are always using carbon brush in  motor instead of using copper or other material brushes. because there are multiple advantages behind in the carbon brushes. so here we will briefly discuss about what are the advantages in using carbon brush in dc motors. Advantages of carbon brush: There are 5 main…
