Question

why Dc current is expensive than ac?​

Answer 1

Explanation:

So we generate AC because AC generators are simpler. We transmit high voltage AC across the grid because its more efficient than low voltage. ... DC generators are more complex. DC has no easy way to change voltage, so DC stations send electricity at the same voltage that it is used at the destination, a low voltage.
