Study Notes
Conductors and Insulators
- Conductors are materials that efficiently transport electricity.
- An insulator is a material that prevents the flow of electric current.
Electric Units and Measurements
- The unit of electric strength is measured in amps.
- Electric pressure is measured in volts, not ohms.
- Electrical energy consumption is quantified in watts.
Types of Electrical Current
- There are two primary forms of electrical current: Alternating Current (AC) and Direct Current (DC).
Safety Devices
- A circuit breaker is a reusable safety device that interrupts current flow during an overload.
- Fuses can also serve as safety devices but are typically single-use.
Electrical Shock
- A local shock refers to an electrical shock that affects a small area of the body.
Electrical Terminology
- The term "load" refers to any electrically powered appliance.
- Frequency measures how many cycles occur per second in an electrical current.
