EE Fundamentals for Job Interviews Abubakar 9 hours ago
For students preparing for core Electrical Engineering roles, I’ve found that Electrical Machines and Power Systems are probably the two areas worth getting especially comfortable with.

For Electrical Machines, I’d make sure you understand transformers beyond just the basic equations. Construction, operating principles, transformer tests, three phase connections, parallel operation, and protection components such as Buchholz relays are all worth knowing.

For Power Systems, I’d focus on transmission fundamentals, including AC vs. DC transmission, high voltage transmission, skin effect, line inductance and capacitance, Ferranti effect, and surge impedance.

One area I wouldn’t overlook is faults and protection. Understanding different types of faults, fault current calculations, relay operation, and circuit breakers seems much more useful for practical interviews than simply memorizing formulas.

I also think it’s worth connecting the theory to actual equipment. Once you understand why a transformer, motor, relay, or breaker behaves the way it does, the interview questions become much easier to reason through rather than just recall.

Curious how others here would rank the EE fundamentals for someone preparing for a core electrical engineering role?

My 2 printers are hard wired to the router but my wife can still get to them through the WiFi in the router. I don't use WiFi much myself. I actually have 2 separate routers with different network access. I have one for guests that only connects to the internet. My network is on another router.

I went with an Epson All in One model largely because it still had supported Drivers for my Windows 8.1 PC.
It set up easily via wireless connection but has since lost communication once already. I'm thinking I may have to connect via Cable if it happens again.

I got rid of my HP (ink) printers 20 years ago. I have had good luck with Brother Lasers. I have 2 that use the same cartridges so supplies are easy but a laser cartridge seems to last for years. One is just a printer that does duplex and the other is a printer copier fax I got in a auction for about $30. I got an HP PCF ink printer at the same auction house, bundled with 2 HP laptops for $90. I kept one laptop, gave one to my grand daughter and I sold the printer for $50. It made the laptops $20 each. They run W/11. I did have to reload them since they were password locked and I couldn't find a hack that opened them. They both had valid MS validation for W/10 so it was pretty painless and MS cajoled me into the free w/11 upgrade.
That HP printer ink subscription is really a scam.
