Question

Which type of current is best for sending electrical energy from one location to another? Why?

Alternating current, because its voltage can be easily raised.
Alternating current, because it uses a lower voltage.
Direct current, because it moves in one direction.
Direct current, because it can be produced from batteries.

Answer 1

The answer is Alternating current, because it can be easily transformed from high to low voltages using transformers. This is important for sending electrical energy over long distances through power lines as lower voltages reduce energy loss due to resistance. In comparison, Direct Current has limitations in voltage transformation, making it less efficient for long-distance power transmission. Additionally, Direct Current can only be produced from batteries or DC generators, which can be expensive and less efficient.
