The different types of layers in PCBs are signal layer, power plane layer, ground plane layer, and silkscreen layer.
Signal layer: Carries electrical signals between components
Power plane layer: Provides power distribution throughout the board
Ground plane layer: Provides a reference point for electrical signals and helps with noise reduction
Silkscreen layer: Contains component outlines, reference designators, and other
Various components like resistors, capacitors, transistors, and diodes are used in circuits to control the flow of electricity.
Resistors: Limit current flow, control voltage levels
Capacitors: Store and release electrical energy
Transistors: Amplify or switch electronic signals
Diodes: Allow current to flow in one direction only

A case study is an appropriate research design when you want to gain concrete, contextual, in-depth knowledge about a specific real-world subject. It allows you to explore the key characteristics, meanings, and implications of the case. Case studies are often a good choice in a thesis or dissertation.
AC current alternates direction periodically, while DC current flows in one direction constantly.
AC current changes direction periodically, typically used in household electricity.
DC current flows in one direction constantly, commonly used in batteries.
AC current is easier to transform voltage levels compared to DC current.
DC current is more efficient for long-distance power transmission.
Examples: AC - power outlets, D
1 ton air conditioner is suitable for small rooms while 2 ton is suitable for larger rooms or spaces.
1 ton air conditioner is suitable for rooms up to 400 square feet.
2 ton air conditioner is suitable for rooms between 400-800 square feet.
Choosing the right tonnage depends on the size of the room and insulation levels.
Factors like ceiling height, number of windows, and climate can also affect the choice of tonnage.
