Q1. What is transformer
Ans. 
A transformer is an electrical device that transfers electrical energy between two or more circuits through electromagnetic induction.
• Consists of two coils of wire (primary and secondary) wrapped around a core

• Primary coil receives electrical input and creates a magnetic field

• Magnetic field induces a voltage in the secondary coil, transferring energy

• Used in power distribution, voltage regulation, and isolation

• Examples: ...read more

Q1. Types of gate in logic
Ans. 
Types of gates in logic are basic building blocks of digital circuits.
• AND gate: outputs true only when all inputs are true (e.g. A AND B)

• OR gate: outputs true when at least one input is true (e.g. A OR B)

• NOT gate: inverts the input (e.g. NOT A)

• NAND gate: combination of AND gate followed by NOT gate

• NOR gate: combination of OR gate followed by NOT gate

• XOR gate: outputs true when inputs are different (e.g. A XOR B)
