Q2. What is Ohms Law & Describe Current Voltage relationship
Ans. 
Ohm's Law states that the current flowing through a conductor is directly proportional to the voltage applied across it, given a constant resistance.
• Ohm's Law: V = I * R (Voltage = Current * Resistance)

• Current is directly proportional to Voltage when Resistance is constant

• Higher voltage leads to higher current flow, and vice versa

• Lower resistance leads to higher current flow, and vice versa

• Example: If a circuit has a v...read more

Q3. What Is KCL and KVL
Ans. 
KCL stands for Kirchhoff's Current Law and KVL stands for Kirchhoff's Voltage Law.
• KCL states that the total current entering a junction is equal to the total current leaving the junction.

• KVL states that the sum of voltage drops around a closed loop in a circuit is equal to the sum of voltage sources in that loop.

• These laws are fundamental principles in circuit analysis and are used to solve complex electrical circuits.
