High Voltage Electrician Interview Questions
Sample answer to the question
In my work as a high voltage electrician, I frequently calculate voltage, current, and resistance to ensure the safety and functionality of electrical systems. When it comes to voltage, I use Ohm's Law (V = I * R) to calculate the voltage drop across a circuit or component. For current, I measure it using a multimeter or clamp meter, and I also calculate it using Ohm's Law (I = V / R). Resistance is a crucial factor in electrical systems, and I measure it using a resistance tester or multimeter. I also use Ohm's Law (R = V / I) to calculate resistance when needed. These calculations are essential for troubleshooting electrical issues, ensuring proper circuit design, and maintaining the integrity of high voltage systems.
