Transmitting Electricty Flashcards
1
Q
Why is an electrical current transmitted at high voltages?
A
It improves the efficiency by reducing heat loss in transmission lines.
2
Q
What are the hazards associated with electricity transmission?
A
You get an electrical shock if one part of your body is at a high voltage than another because this makes an electrical current run through you.
