How many advantages have parallel and series combinations of resistors?

Answer 1

There are so many advantage of parallel and series combination of resistors like if you need resistors with certain values and you have no resistors with enough values then you can create the one you need by connecting several parallel of those you have.

Answer 2

The usual problem here is to find the equivalent resistance, or capacitance. In the following formulae, R is the value of the equivalent resistance, while R1, R2, and R3 are the values of the individual resistances.

For resistors in series, just add up the resistances: R = R1 + R2 + R3...

For resistors in parallel, use the formula 1/R = 1/R1 + 1/R2 + 1/R3... (in the case of two resistances, you can also use the equivalent product-over-sum formula: R = R1 x R2 / (R1 + R2).

For capacitors, the situation reverses. Capacitances in series are calculated like resistors in parallel, i.e., 1/C = 1/C1 + 1/C2..., while capacitances in parallel are calculated like resistances in series.

Answer 3

• we can use the series resistors if we switch on the power supply at a time.
• the advantage of s.r is flowing of current is same.
