How to calculate run capacitor value for inductive motor?

Hi. At the attached circuit diagram you can see the connection of inductive motor (2 coils)with a capacitor and 12VAC source. I would like to know how should i calculate the right value of the C1 capacitor in order to achieved a 90° shift in the capacitor-coil branch,so the motor will spin well?(according to the […]

Find v1=? and v2=? for the circuit

This is my solution,but i have a problem with doing a node analysis for node 2 and 3.In my textbook the solution is like this: (2+i1+i1)V1 -2VO -i1V2=0 and(1-i2+i1)V2-i1V1=5

Why is the pole of RC circuit 1/RC instead of -1/RC?

In a RC circuit, we choose the voltage of capacitance as the output voltage. Then the transfer function is 1/(1+RCs). According to the definition of pole, let 1+RCs=0, then s=-1/(RC) Why I have seen so many times on text books that the pole is 1/RC? Thanks!

12V Pulse circuit to operate a double coil latching relay uses no power unless switching

I have this double coil latching relay and I need a circuit that will provide a pulse to switch it on. After doing the pulse I don’t want it to use any power. There are two sides to the circuit, one to turn the latching relay and another to turn it off. I’m using the […]

Power suply 300V regulated with LM317

I try to build a 300V voltage regulator using a LM317, which should be designed for 100 mA, but the circuit does not behave as I thought. I loaded the circuit with 27K which is a current of 11 mA, and set the voltage regulator to 300 volt over the planned 22K in parallel with […]

What does Nu (ν) prefix mean?

Stumbled upon this in ZVN4525E6 datasheet: Zero Gate Voltage Drain Current (IDSS): 35 νA @ VDS = 250V, VGS = 0V The letter is U+03BD and it is not in any common unit prefixes that I know. My guess this is either substitute for “nano” (since capital Nu is “N”), or some weird expression of […]

Diode OR or transistor OR circuit?

I need a circuit that converts a 3.3V signal into a 24V signal. But I also need to be able to activate the 24V signal using a PCB switch. I can do it in two ways, using a diode OR or using a transistor OR, which one is better? They both look ok in the […]

Replacing capacitors in older electronics

I was working on a supplementary power supply board in an old arcade cabinet. It has a capacitor with some markings that I was unable to identify and was curious if they were important. Also, I would like any advice that could help me avoid damaging the arcade. The markings on the capacitor that I […]
