Yeah, that's the rough idea. You don't write much, so I can't say much more.

The purpose of an earth ground is a compromise of various risks. The earth itself is not some absolute 0 V value. Such doesn't exist. And it is possible, with respect to a lamp stand for example, that...

@Melody although you mention transistors, it is better if you focus on the higher level, first. I suggest you get a book called "Bebop Bytes Back: An Unconventional Guide to Computers" by Clive...

Answer by periblepsis for 7-segment display driver question
I did find a minimization error. See below.some initial thoughtsA 7447 7-seg decoder uses 4 binary inputs, not 3. But I take it that this is to be only have 3 binary inputs and works only for 0 to 7....

Answer by periblepsis for Why Is The Voltage and Current Not What I Calculated?
The problem with your thinking is that you subtracted the LED voltage from the supply voltage to get the remaining voltage that must be dropped by a resistor. Normally, that thinking process is valid,...

View ArticleComment by periblepsis on Current change through inductor is abrupt
@FarhanS You are right. Let's put that to bed. At 2 s, the inductor current is 6 A. Suddenly, there is only a source for 2 A. That situation isn't possible. Following the math, universe would be...
View ArticleComment by periblepsis on Same formulas give different answers
@FarhanS Good. Normally when I see something like \$I_\text{L} = \frac1{L}\int V_\text{L}\:\text{d}t\$, I immediately do this: \$\frac{\text{d}}{\text{d}t}\left\{I_\text{L}\right\} =...

There is a datasheet on the LEDs. Luckily. And provided by me in comments quite a while ago.

I am so impressed! Good work so far. I think I would also replace the three capacitors you mentioned. And yes, if you have ceramics at those magnitudes of value (do you?) then the only question I have...
View ArticleComment by periblepsis on Negative resistance and infinite power?
@FarhanS I get that the Thevenin resistance is -1363.63636363637 Ohms. Not a positive value. Injecting a 1 A current causes the voltage to go more negative. Not more positive. Perhaps this is why you...

Skipping the transformer/load, this stage obviously is not a power stage. Yet, on the right is a 50 Ohm termination, which tells me that this should be a power stage. That juxtaposition bothers me...

MikeW, are there two R5 resistors in both diagrams? Even if one of them doesn't contribute, there probably shouldn't be two devices with the same name.
