how we select ac fuse rating of an power inverter???
If an electrical component has a positive temperature coefficient, how come such components have high power losses due to heat if current decreases when resistance increases? assuming power given by I^2*R whereby the Resistance is infinite.
hi Is there any possibilities to find out the rotation of a shaft or something else by using electromagnectic waves or by IR rays.If s then can v change the dir., of rotation of the same by remotely?& how? plz dn't any1 say "NO r CAN'T"

How can find thermal state value in relay for calculate thermal overload.
WE know that for Inductor X=2pifL,In DC f=0,then X=0 so,V=IX=0;But In the DC excitation of rotor of AC generator,DC motor field coil which coils are inductor so why does not applying DC voltage short the rotor coil of AC generator and field coil of motor?If it would then DC source might be damaged but it is not happened.
