Question 91

An industrial park is to be supplied with electrical energy from a remote power station. To transmit power over long distances with minimal energy loss, transformers are used to change the voltage. Which type of current must be used to operate these transformers, and what level of voltage should be used in the long-distance transmission lines?

A

Alternating current (a.c.) and high voltage

B

Alternating current (a.c.) and low voltage

C

Direct current (d.c.) and high voltage

D

Direct current (d.c.) and low voltage
