This should be pretty basic but I want to clarify some: I = dQ/dt, so that means that I is the derivative of q(t) right? So if I'm given q(t) = (7t^2 - 2t +3) pC and told that time is dimensionless ...
This is a really simple question. But I'm seeing some confusing behavior in an experiment I'm trying to make sense of. So I'm trying to see if my understanding of theory is wrong. Wikipedia says: ...
It's said in books that a circuit is a closed path and thus that electrons come back to the source. If that's the case, what would happen when there were an earth fault in a circuit? How would the ...
I have an AC adapter at home that reads (roughly) the following: uses 220-240v AC 50Hz at 0.2A produces 12V DC at 5A I'm a little surprised that it uses 0.2 amps and produces upto 5. Here's what ...
What parameters affect battery charge time? For example if we're interested in designing a charger for mobile batteries, what parameters should be considered? What happens if a little higher voltage ...
While reading "Electronics for dummies" went through the following block and I realised that I have some uncleared concepts about electricity: Electrostatic discharge involves very high voltages ...
