Okay so I am having this problem with a transistor overheating in a motor control circuit and I am not exactly sure why it is overheating. There is a PWM signal being used to power the transistor from an MSP430 microcontroller. I am using a standard 1N004 kickback diode for the motor and an...

Hi there, I'm struggling to wrap my head around a 'should-be-simple' problem involving an RL circuit. Referring to the image I've pasted below, what happens if we were to remove switch 1, and instead created a scenario where switch 2 simply opens? Where would the current go in the inductor? I...

How large would a superconducting magnetic energy storage device be if it were to safely carry 100 kilowatt-hours of energy? How much cryogen (liquid nitrogen) would it consume per hour if the device were made from high-temperature superconducting materials (YBCO or similar).

Hello everyone , my name is Cynthia. Currently, I am an second-year university student majoring in Electrical Engineering. The reason why I choose EE is because i want to learn and discover the 'magic' of EE :) I am still a newbie in this field, so I hope I could gain more knowledge here. Thank...

What is the general cost for building a tesla coil. I already have a PVC pipe and wiring, but I know I need a board, power supply, coil, led lights, capacitors, resistors, and semi-conductors, etc. I know there are some things I am missing and I am on a budget. If there are any other supplies...
