Electricity Q & A

I have no knowledge of electrical or electronic circuit diagrams. The circuit diagram above seems to turn a small light bulb on and off with a battery of 6V. I want to turn this into a circuit that turns a 220V incandescent light bulb on and off with 220V electricity. And I wonder if there

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

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? ​

A part of the electric vehicle charger connector has melted. These are cases... No matter how you look at it, I don't think it's possible to overheat only a part of it if it's a mechanical problem. Isn't the inflow of foreign substances the biggest cause? I'm curious about the opinions of experts.

As in the picture When the blue permanent magnet rotates Does the coil around you generate electricity? Think of the Bldc motor in the opposite direction, and if you rotate the center magnet, I think it will generate electricity.

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 simpl

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...

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 installing an additional battery for an e-bike I think you need to add an inverter or other boosting device. Is the motor AC or DC?

I want to check the 3-pin and 4-pin relays. As shown in the figure, explain the inspection method using a general analog tester when the power (battery) is connected and when it is not connected.

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 impossibl

Briefly describe the electronic imbalance.

In the above divide circuit r1 = 100k If r2 = 100k What will be the resistance value on the Vout side? Please tell me how to calculate

Sequence circuit during automatic control, please action When a person passes by, the sensor operates and the motor starts. Timer set value It's possible up to here, but the next one is fine..... ex) When No. 1 person passes, the sensor operates and the motor runs for 25 seconds (the distan
