hallo everyone,
I have a problem which i can't solve. Does somebody know how to solve this problem?? The question is:
A 220 V electric heater has two heating coils which can be switched such that either coil can be used independently or can be connected in series or parallel, yielding a total of four possible configurations.
The warmest setting corresponds to 2000 W and the coolest corresponds to 300 W.
R1 > R2
Determine the resistance of R1 [in Ω].
regards
