1. ### motion sensors

https://www.pcbway.com/project/shareproject/Motion_Sensor_1.html this project have completely describe the instrumentation of sensor and its connection, check this out it will be really help full. connect detail of arduino and ESP32 connections.
2. ### Motion in a magnetic field

flaming right hand rule show the direction of currrent in the megnatic field
3. ### AutoTransformer Question

It means actual winding power handling capacity is only 1015 KVA but this autotransformer can handle 5000 KVA means auto transformer can handle 5 times more power and 5 times smaller than a conventional 2 winding transformer
4. ### Electromangetic Filed fluction

An electromagnet can be used for moving scrap steel from one place to another. In a scrapyard, a crane has a large iron disc that is not a permanent magnet. The crane operator lowers the electromagnet into a pile of scrap steel and then switches on the electricity.

6. ### Average Age to take FE/PE/SE

FE at 23 and PE at 26
7. ### Potentiometer replacement. Any thought?

https://www.pcbway.com/project/shareproject/Potentiometer__Switch___RCA_Socket_PCB_Boards_for_DIY_Audio_Amplifier.html this will help you in doing replacement of the joystick using reed switch. this project discussion will help you understand counter going to the digital pot.
8. ### How to Solve Transformer Open and Short Circuit Test for the CBT Electrical Power PE Exam (Electrical PE Review)

thank you for this video really helpfull.
9. ### Percent Voltage Drop

[email protected] - 480: @ is equal to theta Vd-Value * sqrt(3) 480 [email protected] - 277/480 Vd-Value 277
10. ### Generator internal voltage

ye the answer should be :Vi = Vt + Id*Xd = 1+ 0.97*1.1j = 1.46 pu So, the voltage is 1.46 * 250 kV = 365.6 kV there can be mistake in solution manual.
11. ### Problem 530 (NCEES)

we can use MVA Method, 40MVA in series with 25 MVA (1MVA/.04) and 40 X 25 / (40+25) = 15.38 MVA we find out that Fault is on the 480v bus 15.38MVA/(sqrt(3) * 480e-6MV) = 18,500A
12. ### Code question

clearly mention that 277V is single phase connected across L-N.
13. ### home made electrical components

To create a wirewound resistor, one piece of wire would have to serve as the path for the electrical current to flow from one end of the resistor to the other. To create a resistor with a small resistance (or Ohm) value, use a thicker, shorter wire as the path between the two electrical leads.
