Question

High voltage power transmission leads to

• A. less energy loss during transmission
• B. more energy loss during transmission
• C. high magnitude current
• D. more energy loss due to electromagnetic radiation

Answer 1

The correct option is A less energy loss during transmission

The primary reason that power is transmitted at high voltages is to increase efficiency. The higher the voltage, the lower the current. The lower the current, the lower the resistance losses in the conductors. And when resistance losses are low, energy losses are also low .
