Question

Write the expression for net resistance of two resistors when they are connected in

(a) Series (b) Parallel​

Answer 1

Answer:

PLEASE MARK ME AS BRAINLIST

Step-by-step explanation:

Parallel have a Common Voltage across them and this is true for all parallel connected elements.

So we can define a parallel resistive circuit as one where the resistors are connected to the same two points (or nodes) and is identified by the fact that it has more than one current path connected to a common voltage source. Then in our parallel resistor example below the voltage across resistor R1 equals the voltage across resistor R2

Answer 2

Answer:

if three or more resistors each with the same value are connected in parallel, then the equivalent resistance will be equal to R/n where R is the value of the resistor and n is the number of individual resistances in the combination.

This implies that the total resistance in a series is equal to the sum of the individual resistances. Therefore, for every circuit with N number of resistors connected in series: RN(series)=R1+R2+R3+… +RN.
