What kind of division do you make 360/3=180 duhh. 360/3=120.

With 1K in the emitter, the most Ic you will see with Vcc of 5 volts is 5ma. Take the transistor out and put in shorts and see what currents will be in each path. Do some basic current flow.

Because your NPN transistor is in saturation.? Saturation must be avoided if you want current gain. Plot Vce.? It is less than 30 mV throughout your sweep.? It is saturated.? In fact, the

Hello ,I have build NPN which base is being? biased with a current source ,the? problem that My collector current is very low ?no matter the current i put in the base as shown in the photo and

After heat cycling I also did Line (12volt) and load regulation. Try that at 20 KV. Measuring HV with Elector Static VM. I had to design and fabricate all the test fixtures and write the test

At the time I was working for this company, the requirement was for a Heat/Cool cycle in a Temperature chamber for every production supply. I would put I think about 20 supplies in the chamber and

Mr Dan Khan : Please, can you describe the procces of cycling the power supplies ? Was it to test them ? Age a sample of the production ? Bake a coating ? Other motive ? Thanks ! [email protected]>

Three phase is120 degrees apart! I also worked for a firm making HV (20KV) power supplies for CRT displays. Luckily there was hardly any current available. It was based on a 12 volt square wave

I recently saw a video that said construction sites in England us a split phase 110v line that is 55V on each leg. Giving you 55v to ground if you happen to find yourself in that position. 55V is

Paul, I'm no eggspert but you can modify/customise the diagram to create a new symbol. I haven't done it, but look in the help pages for the method. Tony

110v is for american fairys who are scared of 230v! lol.

i am trying to make a schematic that has an arduino nano at the heart of it,the footprint of the nano v3 in the schematic editor seems to have missing pins and some in the wrong place,any ideas?,i am

In those olden days,? neon bulbs could be used as computer elements.? Flip-Flops in particular.? But the circuits were touchy at best and one of the techniques was the use of radioactivity to make

You have to toggle the USB input data line to the power bank (PB) this will signal the processor or logic in the PB to increase to full voltage and full current within its specifications. ie When you

Wikipedia ( https://en.wikipedia.org/wiki/Neon_lamp ) claims they used a tiny amount of radioactive Krypton, not in the electrodes but in the envelope. Andy

Well ...? The normal thing to do was to power them from the AC mains - but with a series resistor, of course!? They were used as pilot lamps for electronic equipment. Unfortunately, they tended to

I believe it is true that some neon bulbs have a tiny amount of radioactive material inside to improve (lower) the firing voltage.? I read or heard that from a number of sources. But I can't help you

hi, I would like to understand how the various *PowerBank work for mobile phones*.... Let me explain better, I wanted to feed a classic flashing light with The usual timer with IC 555 and an LED
