Question

An electronic device designed to operate at any temperature in the range from -5°C to 72 °C contains pure carbon resistors. By what factor does their resistance increase over this range? Let the initial temperature be 23 °C.

Round your answer to 3 decimal places

Answer 1

$$\frac{R}{R_0}=1+\alpha \Delta T\\ \frac{R}{R_0}=1+(10^{-5})(72-23)=1.0005$$
