Detailed Solution

The above statement is False.
The polarity of the current changes 100 times in a single second in the Alternative current (AC). That's why it's called so. On the other hand, the polarity of the current does not change over time & the so, called direct current(DC).
In our country, mainly, AC is produced at power stations in India. The transmission of AC over long distances is more convenient, whereas the transmission of DC is very costly.
The correct statement would be that the AC and DC both are not the same.
