Voltage = 9.0 V, Current = 20 mA, Capacitor (C) = 10 microF, Resistance before (too high) [R_A = R_B] = 10 k Ohms.
In a a-stable oscillator, calculating the resistance needed for two resistors (R_A = R_B) to discharge and charge a capacitor (C) so that a LED does not blow. Currently my circuit...
Homework Statement
On the diagram below, draw vectors to show the magnitude and direction of the electric forces acting between an alpha particle and an electron.
(++) (-)
(I can do that bit)
Hence state and explain which of the two particles will experience great acceleration...
Alright, sorry. I did not have the original question, and I was looking to see what that may've been. Would you know of any similar questions I could practice?
1. Problem - Notes Jumbled, do not know if I am missing variables or not needed to answer the questions?
Disclaimer: I am good at maths, fine with algebra and derivations, I just forget the formulae and units, especially when I haven't practiced things a lot, such as this topic (other subjects...
