Fig. HW1 shows a DC circuit that contains a 48 V EMF, a fuse, two 0.7 2 resistors and two critical loads Ri and R2. The equivalent resistances of R1 and R2 can change within certain ranges. The range for R2 is between 10 2 and 12 2, but the range for Ri is unknown. The fuse is used to conduct electricity during normal operation but will disconnect the EMF from the circuit when Ri or R2 encounters short-circuit failure. If any fuse with a current rating between 16 A and 36 A can be used to achieve the above protective function in this circuit, what will be the range for R1?
