The study of electronics changes day by day as the technology concerned with transistors and microchips changes. One takes up electronics to understand how electrons move in a conductor, semiconductors, vacuum or gas. Take up the ultimate quiz on basic electronics knowledge and see how far wide your knowledge extends. All the best!
Yes, it damages the voice coil
Yes, it burns out the output transformer
No, it just results in a low level hum noise, as phantom power has a frequency of 60 hz
No, as the same potential is applied to both leads of the voice coil
Yes, if the mic is plugged in while the power is on
