Why two nos. un-tensioned wires are placed inside the PSC poles used by powergrid in RGGVY works.
2 6833i work as a technician at a private company.. i used to take amp reading for certain appliances such as air con.. the problem is when i clamp the neutral, wire there is a current reading.. from my understanding for single phase system neutral should not have current unless if the circuit is not complete.. yet the air con still work
3 5781what will be the effect on a bulb in case its connetion is change from live and neutral to live and ground??? 1) in case of single phase AC supply 2) in case of DC supply.......???
