Question

A carbon resistor is to be used as a thermometer. On a winter day when the temperature is 4 0C, the resistance of the carton resistor is 2161 0. What is the temperature on a spring day nhen the resistance is 2157 7 CTaike the reference temperature To to be 4.0°C, and the temperature coefficient of resistance for carban to be-0.000001) Consider the following (a) what is the potertial diffecence Vaa in the drouit of the fiqure aboe (v 550VR-4.00 n) (b) what is the terminal voeltage of the 5.50 V battery? at d with its negative terminal conneced to the neative teminal of the 8.00 v batery, vhat is the difference of potential Vhc between the terminals of the 5.50 V battery now
