what will happen if instead of neutral we use earth wire as return conductor?if we can use ,then why we are not using in our day to day appliances?please justify the answer
11 33274In power generator sets, when they are coverted from 50hz to 60hz, the kva rating after conversion increases. For example, the manufacturer of a perkins 200kva @ 50Hz generator set has mentioned it to become 220kva after converstion to 60hz. What is the relation between the frequency & the KVA rating. Any formula please.
3 7427how u measure/calculate renge of capacitor,capacitor has no any rating tag.what is the theory of measure of capacitons.
1991have u any web site who can give all electrical sum's to solve counting easy like how to convert 1kw=?Kva.
