Answer / poojitha

let us assume that V1 and v2 be two sources connected in
parallel ..now apply the Kirchhoff voltage law(kvl) ..we get
-V1+V2=0...i.e, V1=V2
hence practically this is not possible ..
also to say two elements are parallel..the voltage across
their terminals should be same..

Answer / ravi shanker

After sometime the voltage of all the battries are same because the batteries which has less voltage draw current from high voltage batteries. In this way low voltage batteries chages itself and high voltage batteries dischage upto that level where voltage level is equal.

Answer / sacchidanand teke

I wouldn't advise you to try this. In first semester we
learned to never connect batteries of different voltages in
parallel. the result will be bad.

Batteries of equal potential must be carefully considered
for this as they should be exactly the same. They will
produce half the current each to the resistor.

Answer / steve

Kirchhoff first law states that" the sum of all the current
coming in and going out through a point is equal to zero"
(Ex: V1+V2-V3=0 where V1=5, V2=5, V3=10}. This shows all the
supplies are from different sources and they are not
interconnected.
Hence the above ans is wrong. The batteries are connected in
parallel and the higher voltage battery's voltage dominates
through the circuit.
Note- We don't know whether it is a rechargeable or dry
battery. I assumed it as a dry battery.

My present SMPS ( +12V, -12V outputs, 1Amp Rating ) was faulty.I donot have similar model however i have two + 12V SMPS available. Can i use both of these SMPS as a replacement to present SMPS by connecting one of SMPS in reverese polarity.
