Question

Three resistors connected in series have potential differences across them labeled /\V1 , /\V2 , and /\V3. What expresses the potential difference taken over the three resistors together

Answer 1

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

Step-by-step 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.
