Why is alternating current more effective at long–distance travel than direct current?
The power lines are made out of conductors.
Transformers increase or decrease voltage as needed.
The AC generator is more efficient.
AC has lower voltage than DC.

The alternating current more effective at long–distance travel than direct current because transformers increase and decrease voltage as needed.

What is alternating current?

Alternating current is an electric current which periodically reverses direction and changes its magnitude continuously with time.

The voltage difference developed through transmission lines is very high,. This reduces the current and minimizes the energy lost through transmission. So, alternating current is chosen over direct current for transmitting electricity. It is much cheaper to change the voltage of an alternating current.

Thus, the alternating current more effective at long–distance travel than direct current because transformers increase and decrease voltage as needed
