Answer 2

Frequency of DC current is 0Hertz (Hz).Frequency indicates the no.of cycles that a wave completed in a second. Since DC current does not move in din wave formation like AC current instead moves continuous motion it have 0hz of frequency.However in India AC current frequency is 50hz and in USA frequency is 60 Hz. That means that AC current completes 50 cycles in a second in India. That indicates the movement of waves 50 times up and down in a second corresponding to the horizontal line.

However DC current accidents are more fatal than AC current since they are direct continuous charges moving in a linline unlike AC current. However Transmission of AC current is cheaper than DC current by transformers and line . However energy loss in transmission of AC current is more than DC current.
