How can I find the values ​​that should go in the blank spaces in the picture? Can someone explain it to me in detail? I listened to the professor's explanation, but I don't understand it at all.

I have a question... For example, I usually have a DC 12V 0.16A motor, but can I run this motor with a 3v battery..?? It is.. The front specifications are specifications for the cooling fan, but they actually rotate even with a 1.5V battery... The specifications are written for each motor... Is this the right thing to say... It's the best, but less than that is okay... I'm curious ...

Hello, I am a person who is going to conduct an amplification circuit experiment using the instrumentation amplifier ad620 element. The circuit diagram says that +9V -9V voltage should be applied to the ad620 device, but I don't know how to apply the -9V negative voltage. Please advise on the simplest way to apply +9V ,-9V voltage. And, if possible, it would be appreciated if you could explain why you need to apply two + and - voltages.

hello In a conductor there are free electrons, If only the positive electrode (+), which has a higher potential than the conductor, is connected at one end, the free electrons in the conductor will all go to the positive electrode, will there be no free electrons in the conductor? If it is impossible, please explain why it is impossible. and, At the positive pole of a conductor connected to a power source and through which current flows, Do free electrons pass through the interface of the conductor and enter the anode?

There are power pole wires behind the house, and the sound of electricity flowing? You know, the sound of electricity. I keep hearing that sound, but it's raining so I'm a little worried. Can I just leave it alone? I don't usually

As far as I know, the load consumes power, so the R load is I understand L load, C load, these are also R The L component (C component) is larger. Should I take it in this sense? As far as I know, L C doesn't consume power, but it's confusing because the word "load" comes after it...

Briefly describe the electronic imbalance.

Medical equipment 220V power fuse keeps blowing.. It's like a delay fuse in the middle white. The existing 6.3A was plugged in, can I upgrade it to 8A and plug it in? ​

Is there still no technology to generate electricity using the explosion of an object? If so, can't we just explode hydrogen to produce electricity?

When an amplifier circuit with a high-band cut-off frequency of 500 [khz] is cascaded in two stages, what is the total high-band cut-off frequency of about [khz]? 1) 120 [khz] 2) 240 [khz] 3) 320 [khz] 4) 500 [khz]

If the current flowing through a resistor is tripled, how many times will the diameter of that resistor increase from the current when the voltage across that resistor remains unchanged?

I'm curious about what makes a CC amplifier better than a CE amplifier.

Nickel-cadmium rechargeable batteries are known to have reduced capacity due to the memory effect when charging after some discharge. It is said that after a full discharge, a full charge is required. The capacity does not decrease when fully charged after overdischarging a nickel-cadmium rechargeable battery. is the correct word? So, I'm curious if overdischarge and complete discharge are the same word or interpreted differently. Do nickel cadmium batteries not lose capacity even if overdischarged? Please share data from credible articles and sites on this.
