• Electrical circuits provide pathways for electricity to flow from the power source to appliances and devices.
• Wiring methods (e.g., Romex, conduit) protect wires and ensure safety.
• Electrical safety is paramount; always turn off power before working on electrical systems.
• Overcurrent protection devices (e.g., fuses, circuit breakers) prevent overloads and short circuits.
• Grounding provides a safe path for electricity in case of a fault.
• Electrical codes and regulations (e.g., National Electrical Code) ensure safe electrical installations.
• Basic electrical skills include wiring outlets, switches, and light fixtures.
• Troubleshooting electrical problems involves identifying and correcting faults in the system.

Cookery

• Cookery involves preparing food for consumption, using various techniques and ingredients.
• Essential cooking equipment includes pots, pans, knives, cutting boards, and measuring tools.
• Different cooking methods (e.g., boiling, frying, baking) affect the taste and texture of food.
• Basic knife skills include chopping, slicing, dicing, and mincing.
• Food safety practices (e.g., proper hand washing, preventing cross-contamination) are crucial to prevent foodborne illnesses.
• Understanding basic recipes and culinary techniques is essential for successful cooking.
• Seasoning and flavoring enhance the taste of food.
• Different cuisines have unique ingredients and cooking styles.
• Meal planning involves selecting and preparing meals that are nutritious and balanced.
• Baking involves using dry heat to cook food, typically in an oven.
• Pastry involves making doughs and fillings for pies, tarts, and other baked goods.

Dressmaking/Tailoring

• Dressmaking/tailoring involves designing, cutting, sewing, and fitting garments.
• Essential sewing equipment includes sewing machines, scissors, measuring tapes, and needles.
• Different types of fabrics have different properties and are suitable for different garments.
• Basic sewing techniques include stitching seams, hemming, and attaching closures.
• Pattern making involves creating templates for garment pieces.
• Garment construction involves assembling fabric pieces to create a finished garment.
• Fitting involves adjusting a garment to achieve a proper fit.
• Alterations involve modifying existing garments to improve their fit or appearance.
• Proper pressing and finishing techniques enhance the appearance of garments.
• Safety precautions in dressmaking/tailoring include using scissors and sewing machines carefully.

Computer System Servicing

• Computer system servicing involves maintaining, repairing, and upgrading computer hardware and software.
• Essential tools include screwdrivers, pliers, antistatic wrist straps, and diagnostic software.
• Computer hardware components include the CPU, motherboard, RAM, hard drive, and graphics card.
• The operating system (OS) manages computer hardware and software resources.
• Software applications perform specific tasks, such as word processing or web browsing.
• Troubleshooting computer problems involves identifying and correcting hardware or software faults.
• Preventive maintenance includes cleaning computer components, updating software, and scanning for viruses.
• Networking involves connecting computers and devices to share resources.
• Computer security measures protect computers from malware and unauthorized access.
• Proper handling of computer components is essential to prevent damage from electrostatic discharge (ESD).
• Data backup and recovery procedures protect against data loss.

Agri-Crop Production

• Agri-crop production involves growing crops for food, feed, and other uses.
• Essential farming equipment includes tractors, plows, harrows, and irrigation systems.
• Soil preparation involves tilling, fertilizing, and amending the soil to create a suitable growing environment.
