Question

Why does the potential difference between resistors varies if they are connected in series and remains same if connected in parallel??

Answer 1

Resistors are said to be connected in series when they are daisy chained together in a single line resulting in a common current flowing through them.The higher the resistance of a conductor the less will be the current flowing through it. So different valued resistors connected in parallel then the currents flowing through them will adjust in such a way that the product of R and I remains the same i.e Voltage remains constant. The flow of current across any branch is dependent on the value of resistance of that branch of the network. If the resistance is high then the current will be low and vice versa.
