Electric current is the flow (movement) of electric charge.
The SI unit of electric current is the ampere (A), which is
equal to a flow of one coulomb of charge per second.
Generally flow of electrons is current.There is a
interconnection between the current,voltage and resistance.
According to ohms law current(i)=voltage(v)/resistance(r).
THE FLOW OF CHARGE IN A DEFINITE DIRECTION IS CALLED
ELECTRIC CURRENT.IF q IS THE CHARGE FLOWING THROUGH ANY
CROSS SECTION OF A CONDUCTOR IN TIME t THEN CURRENT IS GIVEN BY
i=q/t.
ITS UNIT IS AMPERE.
ONE AMPERE OF CURRENT IS SAID TO BE FLOW THROURH ANY WIRE IF
1 COULOMB OF CHARGE FLOW THROUGH IT IN 1 SECOND.
2 Diesel Generators 900KVA connected to the bus bar for
essential load as an alternative for power taken from
11/440V 3KVA Transformer supplying this bus bar. my
question here is in the event of power failure on 11KV side
can I feed the power to 11 KV bus by using the same
transformer as reverse feed, what will be the inrush
current???
power is the product of voltage and current.so we can
measure the value of power just by using ammeter and
voltmeter.......then why do we use a wattmeter?
