- Q1. What is Ohms 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 of the conductor.
Ohm's Law is represented by the formula V = I * R, where V is the voltage, I is the current, and R is the resistance.
It helps in calculating the relationship between voltage, current, and resistance in an electrical circuit.
For example, if a circu...
