Study Notes
Electric Current
- The unit of electric current is the Ampere (A), defined as one coulomb of charge passing through a conductor in one second.
Insulating Materials
- Commonly used insulating material for electrical wires is PVC (Polyvinyl Chloride), which effectively prevents electrical current from escaping and protects users from electric shock.
Grounding
- Grounding refers to the process of connecting electrical installations to the earth, which helps protect against electrical shock and ensures safety by providing a path for fault currents to dissipate safely.
Circuit Breaker
- A circuit breaker serves to automatically interrupt the flow of electrical current when a fault or overload occurs, preventing potential damage to electrical systems and reducing the risk of fire.
Insulated Tools
- Electricians are required to use insulated tools to minimize the risk of electric shock while working on live circuits, enhancing personal safety and reducing the likelihood of accidents.
Multimeter
- A multimeter is an essential tool in electrical work, used to measure voltage, current, and resistance, facilitating troubleshooting and ensuring proper electrical system functioning.
