Question

What are the advantages of Alternative current over direct current?

Answer 1

• The ac is easy to generate than dc.
• It is cheaper to generate ac than dc.
• The ac generators have higher efficiency than dc.
• The loss of energy during transmission is negligible for ac.
• The ac can be easily converted into dc.
• The variation of ac can easily be done using transformers either step up or step down.
