Combination of Resistors with Temperature Effect

Combination of Resistors with Temperature Effect

### Formula

$$R_t=R_0(1+\alpha\Delta T)$$

### Terminologies

- Rt → Resistance at temperature t.

- R₀ → Resistance at reference temperature.

- α → Temperature coefficient of resistance.

- ΔT → Change in temperature.

### Conditions / Special Cases

For metals:

$$R\uparrow\ when\ T\uparrow$$

For semiconductors:

$$R\downarrow\ when\ T\uparrow$$

### Usage

- Used in temperature-dependent resistance problems.
