    WheatStone bridge

    The amount of time I have available has nothing to do with the definition of current. Current IS charge flow. It does not have to be iterated twice. If you insist on doing it twice, then why not three or four times to really drive the point home? So do it twice if you must, but know that you...

    WheatStone bridge

    Don't stop now. You can be Lord Byron the poet and say "The stream flowed through the meadow." Or you can be be Sir Isaac Newton and say "A stream exists in the meadow". I believe the more technical approach is appropriate for this forum. Wouldn't it be clearer if the OP said something like...

    WheatStone bridge

    Martaine2003, You cannot have current without something flowing (water, charge, syrup, etc) Therefore, "current to flow" is as redundant as "current flow". "Charge to flow" is OK, but "current to flow" is not. Knowing what something means even if it is presented wrong is gauche. Ever see a...

    WheatStone bridge

    To iimagine: "Current flow" means "charge flow flow" which is redundant and ridiculous. Don't use technical slang when explaining a precise concept. You should instead say current exists, or current is present, or charge flow, or sometimes just plain current. It reduces the confusion and...

    Maximum Voltage in passive capacitive circuit

    To the Ineffable All, I played around with the circuits suggested by the article posted by The Electrician in post #17 of this thread. I got the sinusoidal amplification up to the theoretical maximum of 1.16 zero to peak from 1.0 zero to peak. The equations in the article are interesting and...

    Maximum Voltage in passive capacitive circuit

    Nevertheless, phase shift can be an important part of a circuit, especially an oscillator. Not the circuit I presented, and the circuits shown in the reference submitted my the Electrician. Those circuits have a zero phase shift at a particular frequency. That is a stone cold fact. And...

    Maximum Voltage in passive capacitive circuit

    Interesting article. It is going to take some time to study. Those guys had to work out those equations by hand. Lots of work involved. Also of interest are some of the advertised components that are no longer available or rarely found, like multi-section capacitors. Ratch

    Maximum Voltage in passive capacitive circuit

    The IEEE references are useless to anyone who does not live close to a library that racks that 1951 journal, or is not a member of IEEE. The circuit in stack exchange does not have a phase shift of zero degrees when its gain is greater than 1. That makes it less useful. Tell me if I am...

    But not in a linear manner like a voltage amplifier or transformer does. Ratch

    Maximum Voltage in passive capacitive circuit

    OK, I see your point. I should not have commented on your observation. I think we both agree my circuit is not a phase shifter. Ratch

    Maximum Voltage in passive capacitive circuit

    The difference is that the stray inductance present is mostly compensated for when necessary and rarely used as a primary component in the circuit design. Ratch

    Maximum Voltage in passive capacitive circuit

    The circuit above is really a phase shift oscillator. The 3 caps and resistors shift the phase 180°. The loss of voltage across the 3 RC network is compensated by the voltage gain of the common emitter transistor. The circuit presented by me has no phase shift and actually amplifies the input...

    Maximum Voltage in passive capacitive circuit

    Not quite. The RC network actually increases the voltage at a zero phase shift. Ratch

    Maximum Voltage in passive capacitive circuit

    The following is a passive circuit that contains only capacitance and resistance. No overshoot and no ringing. The output is at zero phase with respect to the input at a particular frequency, and the voltage gain is enough to insure enough feedback to make an oscillator. The transfer function...

    My Vacation

    The now diminished Kodak Film Company once said that tourists sent in more scenic color film about Utah to be developed than any other state. Now, you know why. There are many other national parks in Utah besides the ones featured in my submission. Of course, nowadays the pics are recorded on...

    How to convert J/mol-K to BTU/mol-R?

    The book's figure of 1545 is for English units of lbf-ft, rankine,and lb-moles. However, the book does not tell you that. Get a different text book. Ratch

    How to convert J/mol-K to BTU/mol-R?

    Me thinks you have your units scrambled. I did the calculation for units of calories/(mole-kelvin) and I get 1.986. See below. Ratch

    LC circuit

    Tsk, tsk, you really are lost in the wilderness. You cannot combine the two capacitors because only one cap has a charge imbalance on it. How is that going to affect the "equivalent" capacitor? So, one cap has a voltaqe across it and the other cap does not. Do you know what that voltage is...
