hi,

According to electric potential characteristics.

Electric potential flows from higher potential to lower potential.

i came across strange circuit one of the study material.

Imagine there are 2 power supplies.

V1=10V

V2=5V

if i connect a bulb between postive terminal of V1(10V) to the postive terminal of V2(5V)

will the bulb glow.

My assumption is since V1 is at 10v and V2 is at 5V the bulb should glow.

Please correct me if iam wrong.

see this circuit.

Navigate to 6.1 where two voltage sources are connected in parallel and they have applied KVL to this.

I would be grateful if you can give me some explanation....
for the above example and my question.

Regards,
Rohit

Simply stated, a difference in potential will cause current flow in a conductor. Your lamp will have 5 volts across it, and so some amount of current will pass through the filament.
