The Difference Between AC and DC Current – A Guide for Class 10 Students

Introduction

Electricity is an essential part of modern life, and understanding the basics of it is crucial. Two kinds of electric current, AC (alternating current) and DC (direct current) are widely used in our daily lives. They are fundamentally different from one another, and this article will explore their differences in more detail.

What is AC current?

AC current is a type of electrical current that oscillates back and forth, changing direction periodically. The frequency of these reversals is measured in Hertz (Hz). The electricity that powers our homes and buildings runs on AC current. AC current is generated by power plants and transmitted through power lines to homes and businesses.

What is DC current?

DC current, on the other hand, flows only in a single direction, from the positive to the negative electrode. It is commonly used to power small electronic devices such as smartphones, laptops, and batteries. DC current is generally stored in batteries and used to power devices that are not directly connected to the power grid.

The difference between AC and DC current

The primary difference between AC and DC current is the direction in which they flow. AC current oscillates back and forth, changing directions periodically. In contrast, DC current flows only in one direction, from the positive to the negative electrode.

Another significant difference between the two is the way in which they are generated. AC current is generated by power plants and is transmitted through power lines to homes and businesses. In contrast, DC current is typically stored in batteries and used to power small electronic devices.

Conclusion

In summary, AC and DC current are fundamentally different from each other. AC current oscillates back and forth, changing direction periodically, and is commonly used to power homes and businesses. In contrast, DC current flows only in one direction and is commonly used to power small electronic devices. Understanding the basics of these two types of current is essential for anyone interested in the field of electricity.

AC (Alternating Current) is a type of electrical current where the flow of electrons changes direction periodically. The direction of the current changes continuously, and the voltage also changes its polarity. AC is used to transmit electrical energy over long distances and is commonly found in our homes, offices, and other electrical devices.

DC (Direct Current) is a type of electrical current where the flow of electrons moves in only one direction. The voltage remains constant, and the polarity of the current does not change. DC is used in batteries, electronic devices, and electric vehicles.

The key differences between AC and DC current include:
– Direction: AC current changes direction periodically, whereas DC current flows in one direction only.
– Voltage: AC current’s voltage changes polarity, whereas DC current maintains a constant voltage.
– Usage: AC current is used in electrical power transmission over long distances, whereas DC current is used in electronic devices, batteries, and electric vehicles.
