out of alternating current and direct current which one is used in tansmission of electric power over long distances and why
Answers
Answer:
AC can be stepped up and down in voltage very easily by transformers and the bigger the voltage the lesser the current. You tend to get less losses to resistance when distributing AC over long distances too. You can use thinner wires which means they’re cheaper to make and suspend.
At the power station you can ramp up to thousands of volts and very little current through a step-up transformer. In the UK commonly seen voltages at the consumer end are 230V (residential, commercial, light industry) and 440V (industrial) and the same high voltages sent from the power station are ramped down again through a step-down transformer. In this way you get current back.
It’s much easier to generate AC than DC too due to the way the generators turn.
Hope this helps. :D
