AI Thread Summary
An input impedance of 1MΩ for a voltage probe is considered standard for oscilloscopes. Typically, a "10X" probe has a higher impedance of 10MΩ. Low impedance probes are available for high-frequency signals. The 1MΩ impedance is widely accepted and commonly used in physics labs. Understanding these values is crucial for accurate measurements in experiments.

I am working on a physics lab and wonder if an input impendece of +/-10V input 1M (for a voltage probe) is high resistance or low resistance.

Can anyone help?
Thanks!

A 1M probe is fairly "standard" as far as oscilloscopes go. A "10X" probe typically is 10M. There are also "Low Impedance Probes" for high frequency signals. The above article will define them for you, but, in general, 1M is the most common.

Thread 'The Physics of unloading sand from a barge'

I think it's easist first to watch a short vidio clip I find these videos very relaxing to watch .. I got to thinking is this being done in the most efficient way? The sand has to be suspended in the water to move it to the outlet ... The faster the water , the more turbulance and the sand stays suspended, so it seems to me the rule of thumb is the hose be aimed towards the outlet at all times .. Many times the workers hit the sand directly which will greatly reduce the water...

Thread 'Why can't Solar panels be hemispherical, or a curved strip type?'

comparing a flat solar panel of area 2π r² and a hemisphere of the same area, the hemispherical solar panel would only occupy the area π r² of while the flat panel would occupy an entire 2π r² of land. wouldn't the hemispherical version have the same area of panel exposed to the sun, occupy less land space and can therefore increase the number of panels one land can have fitted? this would increase the power output proportionally as well. when I searched it up I wasn't satisfied with...
