Question 1:
Give the law of combination of resistances in series.

Lakhmir Singh Physics Class 10

Answer 1

Hii There!!

The law of combination of resistances in series states that, the resultant resistance of the resistors is the sum of their individual resistances.

That is ;
R resultant = R1+R2+R3......

Answer 2

Let Xs be the effective resistance of the two resistors in series, and V be the potential difference across the ends. Thus, when a number ofresistors are connected in series, the effective resistance is equal to the sum of the individual resistances. This is called the law of combination of resistances in series.
