A hotplate on an electric cooker contains two identical resistors. The switch has three positions. position 1 The two resistors are connected in series to the mains supply. position 2 The two resistors are connected in parallel to the mains supply. position 3 Just one resistor is connected to the mains supply. Which positions correspond to the low, the medium and the high power settings?

1. Alow power: 1, medium power: 2, high power: 3
2. Blow power: 1, medium power: 3, high power: 2
3. Clow power: 3, medium power: 1, high power: 2
4. Dlow power: 3, medium power: 2, high power: 1
