For sinusoidal signals, the current flowing through a component and the voltage across it are not necessarily in phase. How does this phase difference occur? This knowledge is very important, because
[color=#444444][font=Tahoma,]I need help, what is the model of the transistor in the picture, and which manufacturer made it? Thank you very much!!! [/font][/color]
I want to build a substation control and protection system. I have a DE1-SoC development board. I plan to use the SoC function to develop TCP/IP on an embedded operating system, and other logic functi
