Compare and contrast the advantages and disadvantages of AC and DC currents in terms oftransmission and use in various applications

AC Current:

Advantages:

1. AC current can be easily converted from high voltage to low voltage and vice versa using transformers. This makes it ideal for long-distance transmission as high voltage can be used to reduce power loss.
2. AC current is safer to use because it changes its direction periodically, reducing the risk of electric shock.
3. AC current is used in most domestic appliances and in industrial applications because of its ease of generation and transformation.

Disadvantages:

1. AC current can cause more electrical interference in other devices because of its changing direction.
2. AC systems can be more complex to design and manage because they need to handle the changing direction of current and voltage.

DC Current:

Advantages:

1. DC current is more efficient for short-distance transmission because it doesn't lose as much energy to resistance as AC does.
2. DC current is better for small, sensitive electronic devices like laptops and phones because it provides a constant voltage.
3. DC current is easier to store in batteries.

Disadvantages:

1. DC current cannot be easily transformed from high voltage to low voltage, making it less suitable for long-distance transmission.
2. DC current can be more dangerous because it always flows in one direction, increasing the risk of electric shock.
3. DC systems can be more expensive to install and maintain because they often require converters to change the voltage.
