ΔΦ / Δt term also take frequency into account. More the frequency, more will be the value of ΔΦ / Δt. Flux is due to magnetic motive force which is a function of current. Suppose current is i=cos(2*pi*f*t), taking rate of change of this current will move 2*pi*f outside and voltage will have a...
Jimmy's answer is correct. It would be more interesting if you could find the underlying mechanism to generate these characters. It looks so simple when you know it. Obviously not so simple to guess it first.
Hint: This message is one to one correspondance between English alphabets and the alphabets you can see in the shape above.
Sorry, I can't write so long a text so as to be applied to frequency analysis. Anyway the words written are so familiar to you all!
Will someone tell what does this code say?
Sorry for my poor use of free hand tool. All lines to be considered straight.First character has been drawn bold but it does not matter.
I have observed that reversing the polarity of any IC circuit gets it too much hot. You might use any cheap/faulty IC circuit with the metallic plate of requiered dimension attached like heat sink.
You can also use high wattage resistors. Resistence needs to be calculated for the given...
Using diodes for voltage regulation is a not a very good selection. You might consider using fixed voltage regulator IC's like 7805 (A 3-terminal device with 5 volts output), 7809 etc or LM17.
funops,
You better start a new thread.
I have seen a lot of times electronics equipment failiures attributed to high voltage surges by the vendor. I have never heared a bulb or light becoming victim of that surge.
What circuit it is? It might help understand the device.
I guess it to be some radio circuit because of large number of descrete components and small capacitors. The said component might be a transformer or an inductor and a capacitor togather.
