Question

obtain expression for the equivalent resistance when resistors are connected in series combination​

Answer 1

Answer:

Explanation:

Let there be three resistor of resistance R1,R2,R3 connected in series to battery of voltage V.

In series connection same current passes through all resistors.

The sum of voltage of different resistors gives the total voltage

Let the voltages be V1,V2,V3

Total voltage(V)= V1+ V2+V3

According to ohm's law v=IR

So,

IR=IR1+IR2+IR3

Taking I common from both sides

R=R1+R2+R3
