Two wires A and B made from two different materials have
temperature coefficient of resistance equal to 0.0019 and 0.0019
ohm per degree Celsius, respectively. It is desired to make a coil
of wire having a resistance of 1219 ohms with a temperature
coefficient of 0.001, using suitable lengths of the two given wires
connected in series. Determine the required length of wire A. Put
an illustration figute with compelte solutions, step by step,
kindly handwritten it. THank you!
