Flow of current when sources are connected in ||?

series combination of ideal current source n voltage source is equivalent to ideal current source itself.



parallel combination of d above will be equivalent 2 ideal voltage source.



so wen 2 voltage sources are connected in parallel d total current will be=(V1-V2)/(Z1+Z2).



wen 1 voltage source n 1 current source are connected in Parallel den its equivalent 2 voltage source n d current=V/Z.



wen 2 current sources are connected in parallel den total current=(I1+I2)



wen 2 volg sources r in parallel or 2 currnt sources in series den convert both voltage sources into current sources and both currnt sources into volg sources respectively n den find out d current.

Basically, when more current is needed to flow then sources of equal potential(for dc only)connected in parallel there are no voltage increase but amount of current increases in parallel connection and current send by each source is I/n (where n is no of equal voltage sources). For ac this can be achieved by exact phasor matching between the sources.

It is a bad idea to connect voltage sources in parallel, because a huge current will result is they are not very nearly the same value. The current will be (V1-V2)/(R1+R2) where V is the voltages and R is the equivalent resistances of the sources.

in Parallel operation of sources for driving a load , current flow is shared by both sources. Amount of load shared by each source depends upon their voltage levels. the one which has high voltage will share major part of it.

amperes(current) will same Voltage would also b same if u use capacitor
