Mnemonic triangle

Knighthawk_140
Knighthawk_140 17 days ago

Hello

Here is my custom mnemonic math triangle for constant current ramp work. I have this time and date stamped on youtube.

T = Time, V = Voltage, I = Constant Current & C = Capacitance

Enjoy

    looks like a jet turbine :-) compression, ignition, delta temperature , delta Velocity then whoosh !

    I think it's easier to derive from the formula; the arrangement of the four variables in a triangle doesn't work (whereas with three variables, the V=IR triangle makes sense, and same for other relationships…

    Nice mnemonic! Triangles like this make it much easier to remember the relationships when working with capacitor ramp circuits. Simple visual tricks like these are actually very useful when doing quick calculations or explaining concepts. Thanks for sharing it.

    How interesting - to me it looks like those meaningless diagrams that people use to illustrate corporate time-wasting presentations Slight smile

    The equation is T = (C * dV)/I

    or dV = (T * I) / C

    (dV because its the change in V while I  and C are constant)

    I just can't see how the diagram shows that.

    If a vertical bar means * and a horizontal bar means / then what does the horizontal bar below T mean ?

    I can't work out a consistent decode of the diagram.

    I know that some people associate colours with numbers or letters (synesthesia) - I don't.

    Maybe "seeing" this diagram is a similar thing.

    Well Doug, I probably won't forget that .....

    But I think I'll stick with classical maths notation when I need to do sums.
