Q2. What is Ohm's law?
Ans. 
Ohm's law states that the current flowing through a conductor is directly proportional to the voltage applied across it, and inversely proportional to the resistance of the conductor.
• Ohm's law is represented by the formula V = I * R, where V is voltage, I is current, and R is resistance.

• It helps in calculating the current flowing through a circuit when the voltage and resistance are known.

• It can also be used to determi...read more
