Why is there a different voltage on the heating elements in the electric oven?
Hello! Help to sort out such a problem. In the electric oven costs 6 ten. Three above and three below. Each triple is connected in series with each other and each triple has its own switch to three positions. The first is off, the second and third workers. The instructions say for some reason only three. When measuring voltage on each heating element in position 3, the average heating voltage does not show, the two extreme ones show 220V. In position 2, the voltage shows on all three tena, but far from 220. Tell me why?

Hello! What you described is clearly not a serial connection. Maybe you write a model of the furnace, maybe there is a diagram in the instructions. Judging by the description, this is more like circuits with contactors or packet switches.
In position 2, they can and are connected in series, at least this is indicated by the fact that the voltage is different from 220. By logic, I will assume that the voltage is divided into three ten, and on each of them the multimeter shows a volt of 70. Accordingly, the heating in 2 positions are weaker than in 3.
In the third position, 220V on EVERY ten or two combined? If on each, then the heating is most likely stronger than at position 2. They turn on in parallel without the third ten.
And the scheme there is like this, only here there are 5 positions - 4 workers, organized through a packet switch, watch the right side. Where there is a point, there the circuit closes from the arrow to the electric heater. In the zero position, everything is turned off, in the first position, two chains of 2 heating elements in series, in position 2 only the top, in position 3 only the lower ones (maybe they create more temperature, because the heat rises up) in 4 position - everything is turned on in parallel. So you have the type of this.
