Question

Why is Current same and Potential Difference is different in a series resistance?

Why is Current differnt and Potential Difference is same in a parallel resistance?

Answer 1

The voltage developed across the branch is directly proportional to the current flowing through it and it's resistance. Thus, resistors connected in parallel have equal potential differences across them.





This means that if you add together the voltages across each component connected in series, the total equals the voltage of the power supply. ... If resistors connected in series are not the same then the potential difference is larger across the larger of the resistors.
