Answer / k.prakashchandra
This problem can be solved using fractions also.Work done in
one day is 1/14. Out of this, A' contribution is 2/3and of B
itis 1/3.So A does 1/14 x 2/3 i.e. 2/42 of the work and B
1/42.Hence A alone takes 21 days to complete the work ,and B
42 days.

my UPS suddenly goes off and all panel light also blow off.This happens even main electric supply is not interrupted.After some time it automatically starts functioning normally.Batteries are new.
Direction of flow of active power and reactive power with logic?
How to test IR testing & magnetic balance test
why we are using large cross section cable at load side and small at other (11kv to trsfr)side of transformer? when the load increses current at both side increases,right?
What is UPS?
Hi, I've just got into my electrical engineering course and I need some help with a question of mine here. During a site visit, we were shown a main LT panel which has switchgears, ammeters and different kinds of relays and the distribution network from that panel. In the main LT panel I've noted down the current readings as Ir - 163A, Iy - 150A and Ib - 147A. The Line to Line voltage is 415 V at 50 Hz and Line to Neutral voltage is 230V at 50 Hz. From the above details, how would I calculate the kVA rating of transformer? The primary side voltage of the transformer is 11 kV and the secondary side voltage is 415V and the frequency is 50 Hz.
why it is not advisable to run low rating (19KVA) DG sets in parallel for long durations even though they are provided with droop ckts (QDC)
why the excitation is necessary to produce the reactive power
