1.	Electrical energy is transmitted over large distances at high alternating voltages. Which of the following statements is (are) correct?A. For a given power level, there is a lower current.B. Lower current implies less power less.C. Transmission lines can be made thinner.D. It is easy reduce the voltage at the receving end using step-down transformers
Answer» Correct Answer - 1,2,4 According to relation, `P = EI` when `I` is low, powe loss `(= I^(2) R)` is also low. A step down transformer lowers voltage by increasing current.
