Question

What type of current we get at our homes ac or dc .

Answer 1

AC current we get at our homes.
Because Alternating current and direct current provide two different methods for the transportation of electricity. In DC, the flow of electrons goes in one direction only. In alternating current, the electrons switch back and forth at regular intervals. This also causes the voltage to reverse as the current changes direction. The difference in how these two currents travel to make them useful in different applications. In a house circuit, an alternating current will always be used.
And converting AC to DC is very easy, it requires only very few basic components and the AC to DC conversion can be done efficiently.
But converting DC to AC is much more complicated, needs more components and can be less efficient.
