How do I get this electric motor to run?
ByHerold8
I have this little mini motor that I would like to get running… but unfortunately I don't have any cables for it. How can I get the motor running now (without a high risk of electric shock)? Is this possible with old wires that I could strip and then solder at both ends?
Warming due to compression?
If I compress air at 20 degrees to 7 bar with a compressor, how warm does the air get?
Need quick help with this task?

On the flat roof of farmer Ludwig's pigsty lies at 8:00 a.m. already a 2 m layer of snow. The 12 m x 5 m roof can support a maximum of a load of 28,200 kg. And it keeps snowing: 5 cm per hour! But farmer Ludwig just can't bring himself to clear the snow….
Calculate the water load in the environment given air pressure and relative humidity?
The relative humidity is 50% and the pressure is 1.013 bar. Unfortunately, I can't figure out how to calculate the water load. There's a table for this, but you need the temperature to read the load.
Voltage gradients in food?
Bytheo255
Is there a voltage gradient in food or natural products, or is this pure nonsense? I saw a picture online of a large potato being poured with cola. A charger plugged into the potato (presumably with a very low input voltage) was able to charge a cell phone.
Both are mixed circuits, they have both elements of the series connection and the parallel connection. In the first picture the lower part (both switch and lamp) is in series, the whole part is parallel to the upper lamp.
In the second image, the switches form a parallel circuit, the lamps are connected in series with the switch arrangement.
The first is actually a normal parallel circuit in which the second consumer can optionally be switched on while the first permanently receives current.
The second is a logical OR circuit for three consumers in series.
