Good evening! I bought a cross trainer for myself three weeks ago, and now I suddenly can't feel the resistance anymore. I have the Sportsline cross trainer x11.9. I opened it up, but I don't know anything about it. Yesterday it was still working, and I could feel the resistance increasing in my thighs, but today there's nothing. I would appreciate any help.

Loading...With a fresh 9V battery, a voltage of 9.2V is measured without load (idle). When drawing 100mA, the voltage at the terminals is only 8.6V. What was the internal resistance of the battery? I was able to do that; it was 6 ohms. What terminal voltage do you expect when loaded with an external load…
Hello everyone. I need your help. I need an electronic resistor for a horn speaker to make it a bit quieter. Unfortunately, that's the only way to make these things quieter. 😅 I just have one question. How do I install such a resistor? What do I need to take into account? Unfortunately, my physics…
Because, subjectively speaking, voltage is more lasting than amperes… in terms of strength. What makes a greater "impression" during a lightning strike, amperes or volts?
So, I have a connection like this on a device, but I don't know what kind it is or which plug goes in. Can anyone help? Thanks.
I'm looking for a new connector like this. Searching for terms like solderable screw terminals or conductor terminals, I find similar ones (with screws), but not exactly the one in the picture with 4 pins. The connector is attached to the circuit board with four solder points on the bottom. Can anyone tell me what…
Hi, I've noticed recently that many people are switching to battery-powered devices. Be it the lawnmower, the hedge trimmer or the grass trimmer. How come? I'm not really a big fan of battery-powered devices these days. How do you see this? Do you perhaps even have smart helpers at home? (Robot lawnmower, robot vacuum, etc.)…
Most trainers have a part in the vicinity of the flywheel where strong permanent magnets are located.
This part is then moved mechanically to this large flywheel or away via an adjusting motor.
However, there are also pure electromagnetic systems that work via a coil.
The more current then flows through, the stronger the flywheel is then braked.
The pedal resistance (watt) is generated by an electronically generated magnetic field (field coil principle).
These systems are used on stepper as well as on home trainers (bicycles).
