Study Notes
Electrical Fundamentals
- The flow of electrical charge is from negative to positive terminals.
Units of Measurement
- The unit of electrical resistance is the Ohm (Ω).
- The measure of electrical potential difference is the Volt (V).
Electric Current
- The SI unit of electric current is the Ampere (A).
Conduction of Electricity
- Copper is a material commonly used as a conductor of electricity due to its high conductivity and low resistivity.
Circuit Components
- A resistor is a component in an electric circuit that reduces the voltage or current by converting some of the energy into heat, thereby controlling the flow of electrical energy.
