Q2. Define the ohm law
Ans. 
Ohm's Law states that the current flowing through a conductor is directly proportional to the voltage across it and inversely proportional to the resistance.
• Ohm's Law is represented by the formula V = IR, where V is voltage, I is current, and R is resistance.

• It helps in calculating the relationship between voltage, current, and resistance in an electrical circuit.

• It is named after the German physicist Georg Simon Ohm w
