We are designing an electric space heater to operate from 120 V. Two heating elements with resistances R1 and R2 are to be used that can be operated in parallel, separately, or in series. The highest power is to be 1840 W, and the lowest power is to be 240 W. Draw a cicuit diagram. a. What are the values needed for R1 and R2?
b. What intermediate power settings are available?
c. What are the limits on the current in the circuit?
