what is servo motor and how it works?
when we gave dc supply to 220v dc motor its rpm is 1200. then we gave 180v. how many rpm of its motor. gave answer with calculation at my ID.... ravizak@ymail.com
if any house we instaled a 1.5 ton ac and its phase cable of wiring is installed but netrual cable of wiring not instaed. my question is that is neutual of house(for other wiring is capable for ac load or a sepeart neutrual wiring required
to vary valtage from 0 - max a variac is necessary . so how to design for high power applications nearly about 200KW power
how will reduce the voltage. if 12volt/250ma transformer toreduce 6 volt
give me atleast four differences between circuit and network
