Q4. What is the ohm's low
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 = IR, where V is the voltage, I is the current, and R is the resistance.

• It helps in calculating the current flowing through a circuit when the voltage and resistance are known, or determining the r...read more
