What does quality factor depend on in resonance?
In both 600/1000 V cable and 450/750 V cable, we can supply 415 V. However for distribution, all utilities are using only 600/100 V instead of 450/750 V. What is the reason?
In how we connect watt meter for open & short circuit test of a single phase transformer.
In Indian Household, generally we receive 220V AC single phase supply. But AC has 2 phases, +ve & -ve. So in +ve half cycle current is flowing...so what happens in the -ve half cycle?? Please illustrate.
Why AC current leads voltage in capacitor and how?
Dear all i am kumaravel. now in chennai. my work is control and relay panel auto cad designing.up to 11kv to 400kv then question is i am improving my knowledge. i want some books name and auther are available for this C&R panel related. plese any one help me
