Assume the RTD in Problem 1 has a resistance of 200 Ω at 50°C, 400 Ω at 100°C, and 600 Ω at 150°C. To what value must you set the other external bridge resistor to maintain a temperature of 125°C?

Problem 1

Show how to connect the CA3079 zero-voltage switch to a 3-wire RTD bridge in order to control a triac-driven heating element.
