Answer 2

Given,

The three resistances are connected in series.

To find,

Derivation of the equivalent resistance expression.

Solution,

We can simply solve this mathematical problem by using the following process.

Let, the three resistances :

First resistor = R1

Second resistor = R2

Third resistor = R3

Equivalent resistance will be the algebraic sum of the above mentioned three resistances.

Equivalent resistance = R1+R2+R3

Hence, the expression for the equivalent resistance will be (R1+R2+R3).
