Circuit Symbol CR: Decoding the Mysterious Ref Designator in Diode . . . Circuit symbol "CR" I have seen in some old schematics that diodes are labeled "CR" as a ref designator instead of D I am just curious what the intention of this was since I have never seen a diode labeled with CR until now CR = crystal rectifier or current rectifier?
What is this electrical component CR - Physics Forums What is this electrical component "CR"? Hey folks, Can anyone give me a hint to what the CR symbol in this wiring diagram might mean? I'm thinking it is some kind of switch The equipment is a solar cell tester Basically it traces I-V curves In the attached picture the pins
Do electrons flow through a battery or is it something else? This is a confusing question I am not sure if electrons flow through the battery from positive terminal to negative terminal against the electric field within the battery; or the electrons deposit on positive plate resulting in a chemical reaction that releases electrons at the negative plate
Electrostatics - spherically symmetric charge density - Physics Forums Homework Statement Imagine a spherically symmetric charge density p(x) = Cr for r≤a and 0 for r>a (a) determine the electric field E(x) and potential V(r) Notice that V(r) and E(x) are continuous at r=a (b) Now suppose additional charge is placed uniformly on the surface at r=a, with
Fundamental Theorem of Line Integral question - Physics Forums The question is suppose that F is an inverse square force field, that is, F(r)=cr |r^3| where c is some constant r = xi + yj + zk Find the work done by F in moving an object from a point P1 along a path to a point P2 in terms of the distances d1 and d2 from those points to the origin
Electron Flow in Car Batteries: Conventional vs. Electron Theory electron conventional theory - which way does electrons actually flow in a car battery? Ok, I'm confused about what I keep being told when I ask car mechanics about the jumpering of car batteries I am hoping someone can help me with understanding which way electrons are actually going to
