I honestly have a little trouble with both linear circuit theory and design. A lot of the class is doing the labs (building circuits and analyzing outputs) and answering both qualitative/quantitative questions about circuits like Common Emitter amplifiers, Diode Clamps, Current Mirrors, etc...

Hello PF, I am currently in an Analog Electronics course that comes with a lab. We use Art of Electronics (AoE) by Horowitz and Hill as our textbook, but after reading through it, I'm starting to feel that it's not as suited for a Physics course as it is for say, an Electrical Engineering...

Homework Statement Consider a metal bar of length L, cross-sectional area A, equilibrium atomic separation x, and Young's modulus E. When a tension force F is applied to the bar, it causes an extension ΔL. Calculate the atomic force constant k by deriving expressions for (a) the number of...

I reworked the problem and found my mistake somewhere when I was trying to simplify the huge radical that came from using the quadratic formula. I finally got the right answer from the book, |v0| > [2E(M+m)/Mm]1/2. In short, the book answer was right, but equation (3) provided by the book and...

The units for 2E would be Joules, or kg (m^2/s^2), while the rest of the values are (m^2/s^2) or v^2, as the m/M units of kg/kg cancel out. Thus, 2E/m seems to work out in terms of units. I continued on the problem using 2E/m, and after tedious amounts of algebra I got that v0 must be at least...

Homework Statement An electron, mass m, collides head-on with mass M, initially at rest. As a result of the collision, a characteristic amount of energy E is stored internally within the atom. What is the minimum initial speed v0 that the electron must have? (Hint: Conservation principles...
