Study Notes
Conductors of Electricity
- Copper is a good conductor of electricity, along with other metals like gold, silver, and aluminum.
Electric Current Measurement
- The unit of measurement for electric current is the ampere (A).
AC and DC Current
- AC (Alternating Current) reverses direction periodically, whereas DC (Direct Current) flows in one direction only.
- AC is commonly used in households, while DC is used in electronic devices like batteries.
Capacitance
- Capacitance is the ability of a device to store electric charge, measured by the amount of electric charge stored per unit of electric potential.
Capacitance Measurement
- The unit of measurement for capacitance is the farad (F).
Factors Affecting Capacitance
- The capacitance of a capacitor is affected by factors like the distance between the plates, the area of the plates, and the material between the plates (dielectric).
- Increasing the area of the plates or decreasing the distance between them increases capacitance, while changing the dielectric material can also affect the capacitance.
