Which equation represents Ohm's Law?

• A. V = I * R
• B. V = P / R
• C. P = V * I
• D. I = P / V

Answer: (A)

Ohm's Law is fundamental in electrical engineering and describes the relationship between voltage, current, and resistance in a circuit. The equation V = I * R represents this relationship clearly, where V is voltage, I is current, and R is resistance. According to this law, the voltage across a conductor is directly proportional to the current flowing through it, provided the temperature remains constant. This means that if you increase the current while keeping the resistance the same, the voltage will increase proportionally, and vice versa. This equation is crucial for circuit analysis and helps in designing and troubleshooting electronic circuits effectively.
