Study Notes
Electrical Circuits and Safety
- The main function of a circuit breaker is to protect an electrical circuit from damage caused by overcurrent or short circuit.
Grounding and Polarization
- A common ground in an electrical system ensures that all equipment is connected to the earth, providing a safe path for electricity to flow in case of a fault.
- A grounding pole in a plug sends extra power away from a device, ensuring safety.
- A polarized plug has one prong larger than the other, ensuring correct polarity and preventing electrical shock.
Conductors and Circuits
- A hot conductor is a wire that carries current from the power source to the equipment in an electrical circuit.
- A ground conductor connects equipment to the earth, providing a safe path for electricity to flow.
Circuit Functionality
- The primary function of an open circuit is to prevent electricity from flowing, usually for safety or maintenance purposes.
Electrical Power
- The unit of electrical power, equal to one amperage under the pressure of one volt, is the watt (W).
Electrical Safety Devices
- A circuit breaker is designed to protect an electrical circuit from damage caused by overcurrent or short circuit.
