Frequently Asked Questions (FAQs)

Q1: What is the process of Thermionic Emission? Ans: Thermionic emission is the release of electrons from a hot metal surface. This occurs when thermal energy gives electrons enough power to overcome the surface barrier of the metal.

Q2: What is the difference between Analogue and Digital signals? Ans: Analogue signals are continuous and vary smoothly over time, whereas digital signals are discrete and consist of only two levels, typically represented as 0 (low) and 1 (high).

Q3: How do Logic Gates function in electronic circuits? Ans: Logic gates act as electronic switches that follow specific rules. They take one or more inputs and produce a single output based on the logical relationship defined for that gate.

Q4: What is the purpose of an OR Gate? Ans: An OR gate produces a high output (1) if at least one of its inputs is high (1). It only gives a low output (0) when all inputs are low.

Q5: Why is a Cathode Ray Oscilloscope (CRO) used in Physics? Ans: A CRO is an incredibly useful tool used to visualize and measure electrical signals, such as voltage changes and wave frequencies, on a screen.
