Solution

The difference between a direct current and an alternating current:

$\begin{matrix} D i r e c t C u r r e n t & A l t e r n a t i n g C u r r e n t 1. I n D i r e c t c u r r e n t, t h e d i r e c t i o n o f c u r r e n t r e m a i n s f i x e d o v e r t h e w h o l e t i m e . & I n A l t e r n a t i n g c u r r e n t, t h e d i r e c t i o n o f c u r r e n t k e e p s o n c h a n g i n g a t r e g u l a r i n t e r v a l s . \end{matrix}$

In India, the AC changes its direction 100 times in one second.
