in non technical way how can u define POWER FACTOR??
What is the permissible value of earth resistance and as per which standard / act / rule ?
what is a diffrence between MCCB, RCCB, MCB, & ELCB ? what is rated current e.g. on motor name plate indicated that is rated curent? what is full load current? If we run D.C. motor with mechanical coupling and we measure voltage on terminal it shows voltage or not ? same in AC also possible ?
what is the difference between ac and electric
