Two resistors with temperature coefficients of resistance `alpha_1` and `alpha_2` have resistances `R_(01)` and `R_(02) ` at `0^@C`. Find the temperature coefficient of the compound resistor consisting of the two resistors connected.
a.. In series and
b. in paralllel

Explanation

To find the temperature coefficient of the compound resistor consisting of two resistors connected in series and parallel, we will follow these steps:

### Part (a): Resistors in Series

1. **Define the resistances and temperature coefficients**:
- Let \( R_{01} \) be the resistance of the first resistor at \( 0^\circ C \) with temperature coefficient \( \alpha_1 \).
- Let \( R_{02} \) be the resistance of the second resistor at \( 0^\circ C \) with temperature coefficient \( \alpha_2 \).
