What is Faraday's law
In a power conditoining unit (inverter) of a solar plant when we measure the d.c. current fed by different strings of solar plates to inverter, the current in the negative wire is less almost by 1 ampere to the current in its positive wire say current in positive wire 5 A , then current in negative wire of the same string is 4 A. Since the current entering should be equal to current leaving then why the current is noticably less in negative wire.

what is the mechanical safety of DG ?
Please, if 1kw is equal to 1.25kva; how then do I know how many kva in 7.5kw?
We are planning to synchronized DG's with our captive plant in the event of black start of plant, but before sync we checked voltage of DG with our plant voltage and it varies from 5 V to 450 V. So in this condition how we can sync DG with plant ?
Two electric lamps 40 W, 220 V each are connected in series across 220 V. What is the power consumed by the connection?
what is the IPC ? & what the uses ?
