AI Thread Summary
The discussion revolves around evaluating the accuracy of a bipolar base emitter voltage calculation. A participant suggests performing a backward calculation by inserting the results for Vbe into the original equations to verify the results. Another participant admits they haven't checked the entire calculation due to its complexity but supports the idea of using backward calculations as a method for confirmation. The conversation emphasizes the importance of validating calculations in electronics. Overall, the thread highlights the need for thorough verification in technical calculations.

Hi again dear friends. , hope all are doing well.
Please could some one evaluate my work and advise me in case any correction is required.
Have a good day

Hi Falcon, did you already try a calculation backwards?
That means: To insert the results for Vbe into the orignal equations?

No
If you advise me to do that , then I will do it.
What about the formulae and method I have chosen, are they correct?

I must admit that I did not check the whole calculation (extensive and hard to read).
Therefore my recommendation. I think, such a calculation backwards is a simple method for confirming the result.
 

Thread 'Why does the amperage go real high if there is a low voltage short?'

I used to be an HVAC technician. One time I had a service call in which there was no power to the thermostat. The thermostat did not have power because the fuse in the air handler was blown. The fuse in the air handler was blown because there was a low voltage short. The rubber coating on one of the thermostat wires was chewed off by a rodent. The exposed metal in the thermostat wire was touching the metal cabinet of the air handler. This was a low voltage short. This low voltage...

Thread 'How might electronics be different if AC voltage was 72V at 45 Hz?'

Hey guys. I have a question related to electricity and alternating current. Say an alien fictional society developed electricity, and settled on a standard like 73V AC current at 46 Hz. How would appliances be designed, and what impact would the lower frequency and voltage have on transformers, wiring, TVs, computers, LEDs, motors, and heating, assuming the laws of physics and technology are the same as on Earth?

Thread 'How Does Jaguar's 1980s V12 Dual Coil Ignition System Enhance Spark Strength?'

Thread 'How Does Jaguar's 1980s V12 Dual Coil Ignition System Enhance Spark Strength?'

I have come across a dual coil ignition system as used by Jaguar on their V12 in the 1980's. It uses two ignition coils with their primary windings wired in parallel. The primary coil has its secondary winding wired to the distributor and then to the spark plugs as is standard practice. However, the auxiliary coil has it secondary winding output sealed off. The purpose of the system was to provide a stronger spark to the plugs, always a difficult task with the very short dwell time of a...
