A hotplate on an electric cooker contains two identical resistors. The switch can be set to three positions. position 1: The two resistors are joined in series to the mains supply. position 2: The two resistors are joined in parallel to the mains supply. position 3: Only one resistor is joined to the mains supply. Which positions match the low, medium and high power settings?
- Alow power 1, medium power 2, high power 3
- Blow power 1, medium power 3, high power 2
- Clow power 3, medium power 1, high power 2
- Dlow power 3, medium power 2, high power 1
