State deffirence between A.C& D.Cat currents

Answer 1

AC stands for alternating current, while DC stands for direct current. The main differences between them are:

1. Direction of flow: In AC, the direction of the current changes periodically, while in DC, the direction of the current flows in only one direction.

2. Frequency: AC has a frequency that varies depending on the application (typically 50 Hz or 60 Hz), while DC has zero frequency.

3. Power transmission: AC is used for long-distance power transmission, while DC is used for shorter distances and more specialized applications.

4. Efficiency: DC tends to be more efficient than AC for certain applications, such as electric vehicles and renewable energy systems.

5. Voltage regulation: AC voltage can be easily regulated using transformers, while DC voltage requires more complex electronics to regulate.

6. Safety: DC is generally considered safer than AC at lower voltages, as there is less risk of electrocution.
