Three resistors connected in series have potential differences across them labeled /\V1 , /\V2 , and /\V3. What expresses the po
Brrunno [24]

Answer:

\Delta V=\Delta V_1+\Delta V_2+\Delta V_3

Explanation:

We are given that three resistors R1, R2 and R3 are connected in series.

Let

Potential difference across R_1=\Delta V_1

Potential difference across R_2=\Delta V_2

Potential difference across R_3=\Delta V_3

We know that in series  combination

Potential difference ,V=V_1+V_2+V_3

Using the formula

\Delta V=\Delta V_1+\Delta V_2+\Delta V_3

Hence, this is required expression for potential difference.
