Difference between ac and dc current?
Difference between AC and DC Current
- AC Current: AC stands for Alternating Current. In AC current, the direction of the flow of electrons changes periodically. The magnitude of the current varies as it moves in a particular direction and then in the opposite direction. The frequency of AC current is measured in Hertz (Hz). The standard frequency for most power grids is 50 Hz or 60 Hz.
- DC Current: DC stands for Direct Current. In DC current, the flow of electrons is always in one direction. The magnitude of the current remains constant as it moves in the same direction. DC current is used in most electronic devices, such as computers, mobile phones, and televisions.
Differences between AC and DC current
- Direction of current: AC current flows in both directions, while DC current flows in only one direction.
- Frequency: The frequency of AC current is measured in Hertz (Hz), while DC current has a constant frequency of 0 Hz.
- Power Transmission: AC current is used for power transmission over long distances. AC current can be easily transformed to higher or lower voltage levels using a transformer. DC current is not suitable for power transmission over long distances.
- Efficiency: AC current is less efficient than DC current for electronic devices, as it requires extra components, such as capacitors and inductors, to convert it to the required voltage level. DC current is more efficient for electronic devices, as it can be used directly without any conversion.
- Cost: AC current is cheaper to generate and transmit than DC current.
- Applications: AC current is commonly used in home appliances, lighting, and power transmission. DC current is commonly used in electronic devices, such as computers, mobile phones, and televisions.
Conclusion
In conclusion, AC and DC currents are two types of electrical currents that differ in their direction, frequency, power transmission, efficiency, cost, and applications. AC current is used for power transmission over long distances and in home appliances, lighting, and power transmission, while DC current is used in most electronic devices.
