Image and Sound Formats: Types and Characteristics
Image Formats: Types and Characteristics
There are several types of image formats, each with its own characteristics and uses:
- Raster Images or Bitmaps: These are formed by many points (pixels) that, as a whole, define the final image. Each of these points has a specific color, luminosity, and contrast. The image files contain the information of the image in a dot matrix (pixels), so-called raster. When you save a bitmap image to a file, the characteristics of all points are stored.
- Vector Images:

RCCB vs ELCB Comparison
| Feature | RCCB (Residual Current Circuit Breaker) | ELCB (Earth Leakage Circuit Breaker) |
|---|---|---|
| Definition | Refers to Residual Current Circuit Breaker. | Refers to Electric Leakage Circuit Breaker. |
| Operation Type | Current-operated device. | Voltage-operated earth leakage device. |
| Leakage Detection | Ensures 100% detection of leakage current; senses both AC and DC leakage. | Can only detect current flowing back through the main earth wire. |
| Connection with Earth Wire | Not connected to the earth wire; trips when |
Circuit Theorems: Vaschy, Thevenin, Norton, and Power Transfer
Vaschy’s Theorems for Null-Action Sources
Vaschy’s Theorem About Electromotive Sources
Enounce: If we add electromotive voltage sources with equal values on all sides converging to a node by serial connection, the source having identical orientations reported to the common node, then the currents from the sides of the circuit remain unchanged.
Vaschy’s Theorem About Current Sources
Enounce: If along a loop of a circuit we add current sources connected in parallel with the sides of the respective loop,

1. Purpose and Scope
The purpose of this investigation is to determine the specific requirements for electrical equipment in operating rooms and intervention halls, and the conditions for installing the receivers in receiving them. The object of this is to meet the requirements of applicable European Directives under the provisions in Article 6 of the Regulation for Low Voltage Electro.
In addition to the local general requirements for sanitary purposes identified in the ITC-BT-28, the detailed requirements

Electrical Circuit
Current Flow in an Electric Circuit
- I = V/R
- I = Q/t
- Unit = Ampere [A]
- Current cannot flow through air.
- Electromotive force (EMF) is responsible for the flow of current through an electric circuit.
- Resistance opposes the flow of current in an electric circuit.
Magnetic Circuit
- Flux flow in a magnetic circuit.
- Φ [Flux] = B x A
- Unit = Weber [Wb]
- Flux can flow through air.
- Magnetomotive force (MMF) is responsible for the flow of flux through a magnetic circuit.
- Reluctance opposes the flow of flux
