A rectifier is an electrical device that converts alternating current (AC) to direct current (DC) by allowing current to flow in only one direction.

• Rectifiers are commonly used in power supplies to convert AC to DC for electronic devices.

• They typically consist of diodes which only allow current to flow in one direction.

• Half-wave and full-wave rectifiers are two common types.

• Examples of rectifiers include bridge rectifiers and voltage doubler circuits.

Chargers are devices used to supply electrical energy to rechargeable batteries or devices. There are various types of chargers available.

• Types of chargers include wall chargers, car chargers, wireless chargers, and fast chargers.

• Chargers can vary in terms of power output, charging speed, and compatibility with different devices.

• Some examples of chargers include USB chargers, laptop chargers, and portable power banks.

Possible problems in the charger include overheating, short circuits, and charging port damage.

• Overheating due to poor ventilation or faulty components

• Short circuits caused by water damage or worn out wiring
