Q1. A power plant uses a transformer to step up the voltage of an alternating current. What is the primary reason for this process?
Answer: Increasing the voltage to reduce the current due to Ohm's law
Explanation: The correct answer is due to Ohm's law, where voltage is directly proportional to current. Increasing voltage reduces current, thus decreasing losses in transmission lines.
