if the voltage across the lamp drops by 1%, the power drawn
will be reduced by how many %?
Answer Posted / wareagle
Watts = E x I
I = E/R
W = E x E/R = .99E x .99E/R = 0.98 watts

What is the need of earthing transformer for delta side of a transformer. (Think of a line section between a star/delta transformer at a grid substation and delta/star transformer at a village. An earthing transformer is there at the delta side of the star/delta transformer at grid substation). As there are no ground reference there will not be fault current if a one phase is grounded. Further L-L phase will be sensed by the primary side of star/delta transformer as a L-G fault. So why an earthing transformer is required at delta side
