Question

what is dicference b/w parallel series and combination series?

Answer 1

Diff. between parallel and series combination :-

Parallel combination -
1. In this combination, all the resistors are connected across same potential difference.
2. The sum of currents flowing through each resistor is equal to the total current entering in combination.
3. In parallel combination we can operate each devices with its individual switch which is not possible in series combination.
4. Equivalent resistance is the algebraic sum of reciprocal of each resistor.
Series combination-
1. Resistors are connected end to end i.e. same current flows through each resistor.
2. Applied voltage is equal to the algebraic sum of the potential differences across each resistor.
3. Equivalent resistance is the algebraic sum of each resistors.


I hope it will help u :)
