|---|---|
| Electrical Service | refers to the installation, operation, maintenance, and repair of electrical systems that provide power. |
| House wiring | is the system of electrical wires installed in a house to distribute electricity safely to lights, outlets, and appliances. |
| Lighting systems | are electrical installations that provide light in homes, buildings, and outdoor areas using lamps, bulbs, and switches. |
| Convenience outlets | are electrical sockets where appliances and devices are plugged in to receive electric power. |
| Circuit breakers and panels | are safety devices that control and protect electrical circuits by automatically stopping the flow of electricity when there is overload or short circuit. |
| Electronics Service | involves working with low voltage devices that control, process, or transmit signals. |
| Radios and televisions | are electronic devices used for communication and entertainment by receiving and displaying sound and images. |
| Computers and mobile phones | are electronic devices used for communication, information processing, and accessing digital services. |
| Audio and video equipment | are electronic devices used to record, amplify, and play sound and images for entertainment or presentations. |

| Electrical vs. Electronics Services | •Electrical Services: Uses high voltage, Focus on power supply, Wiring and lighting, Heavy components •Electronics Services: Uses low voltage, Focus on signal control, Devices and circuits, Small components |
| Voltage (V) | is the electrical pressure that pushes electric current through a circuit. |
| Current (I) | is the flow of electric charge through a conductor. |
| Resistance (R) | is the opposition to the flow of electric current in a circuit. |
| Power (W) | is the rate at which electrical energy is used or consumed. |
| Ohm’s Law | Relationship between voltage, current, and resistance. |
| Amperes (A) | Unit of electric current, |
| Ohm (Ω) | unit of electrical resistance, |
| Volts (V) | unit of electrical voltage. |
| Watt (W) | unit of electrical power. |
| Ohm’s Law Formula | V=I×R |
