alleryWhy is ac voltage preferred over dc voltage for power distribution?
AIt carries more charge per hour
BIt converts easily by transformer
CIt travels faster along the wire
DIt costs less to generate first
Answer & Solution
Correct answer: B. It converts easily by transformer
1. The advantage lies in changing the voltage rather than in the current itself.
2. High voltage cuts transmission losses and low voltage is safe at home.
3. The main reason is that ac voltages can be easily and efficiently converted by transformers.
4. So the answer is easy conversion by transformer.
