Answer / shilpa.r

It states that "In any linear bilateral electrical network
containing more than 1 emf sources,the current that flows
through any piont of network is equal to the algebraic sum
of all the currents that would flow through that point,if
each emf source is considered separately,while all other
emf sources are replaced by their internal resistances"...

Answer / mah

The superposition theorem for electrical circuits states
that for a linear system the response (Voltage or Current)
in any branch of a bilateral linear circuit having more than
one independent source equals the algebraic sum of the
responses caused by each independent source acting alone,
while all other independent sources are replaced by their
internal impedances.

Answer / shubham

In any network made up of linear impedances and countaining more than once source of e.m.f., the current flowing in any branch is the phasor sum of the currents that would flow in that branch if each source were considered separately,all other e.m.f.sources being replaced for the time being,by their respective internal impedances.

please let me know , we have installed two separate motor for fire fighting system 1) 60 hp and 2) 15 hp the load is 74 AMPS and 20 AMPS then tell me the main power cable in Aluminum will be what thickness , the length is 225 mt from the main utility to fire pump house
