Frequently Asked Questions

What is the difference between an NPN and PNP transistor? In an NPN transistor, current flows from collector to emitter when a positive base voltage is applied. In a PNP transistor, current flows from emitter to collector when the base is driven to a lower voltage than the emitter. NPN is more commonly used because electrons have higher mobility than holes.

What is the difference between AM and FM modulation? In AM (Amplitude Modulation), the carrier's amplitude varies with the signal while frequency stays constant. In FM (Frequency Modulation), the carrier's frequency varies with the signal while amplitude stays constant. FM is more resistant to noise and is used for higher quality audio broadcasting.

What is the significance of Thevenin's theorem? Thevenin's theorem allows any linear circuit to be replaced by an equivalent circuit with a single voltage source (Vth) and a series resistance (Rth). This simplifies analysis of complex circuits, especially when examining behavior under varying loads.
