What impact, if any, does the solder mask color have on the electrical and mechanical properties of a PCB
At my place of work, we use soldermask colors as a sort of poke-yoke for manufacturing purposes E.g. Technicians know that green pcb goes with green, blue pcb with blue, etc. This has lead to some ... ...

Capacitor dielectric: Is X7R a direct upgrade over 2C1?
I'm trying to replace a capacitor with an IECQ-CECC 2C1 Dielectric. The supplier has offered a comparable EIA X7R Dielectric. Viewing this comparison document, they are largely identical. However, the ...

Material with fairly high resistivity, but allows flow of charge
Is there a material with fairly high resistivity (at least semi-conductor level), but also allows the flow of charge through it (and subsequently to the ground)? The flow of charge does not need to be ...

Confusion regarding effect of dielectrics on energy stored in a capacitor
If inserting a dielectric has the effect of reducing the magnitude of the electric field in a capacitor (holding all other variables constant), then why is the energy stored in a capacitor directly ...

What is the correlation between dielectric plates and capacitance? [closed]
A project I'm working on requires a capacitor of 37000 uF and a voltage rating of at least 10kV, but every capacitor I find online can only meet one of these standards and is very expensive, so ...

Electrical generator where a dielectric is pulled out of a capacitor
In physics class I learned that removing the dielectric out of a charged capacitor increases the voltage and therefore the energy stored.
Could this effect be used to build a generator? The extra ...
