    Study Notes

    Electric Current and Circuits

    • Electric current is the flow of electricity along a conductor.
    • A complete electric circuit is the path of an electric current from the generating source through the conductor and back to its original source.

    Measuring Electric Current

    • The standard unit for measuring the strength of an electric current is the Ampere (A) or amp.

    Types of Electric Current

    • Alternating Current (AC) is a rapid and interrupted current that flows first in one direction and then the opposite direction.
    • Direct Current (DC) is a constant current that travels in one direction only and produces a chemical reaction.

    Electrodes

    • An anode is a positive electrode.
    • A cathode is a negative electrode.

    Electrical Processes

    • Anaphrosis is the process of forcing substances into tissues using galvanic current from the negative toward the positive pole.
    • Cataphoresis is the process of forcing acidic substances into tissues using galvanic current from the positive toward the negative pole.
    • Desincrustation is the process used to soften and emulsify oil and blackheads in the hair.

    Electrical Devices

    • A converter is an apparatus that changes DC to AC.
    • A circuit breaker is a switch that automatically interrupts or shuts off an electric circuit at the first sign of overload.

    Electric Conductors

    • A conductor is any substance, medium, or material that conducts electricity.

    Types of Electric Current

    • Alternating current (AC) is a type of electric current that rapidly and intermittently changes direction, flowing first in one direction and then the opposite direction.
    • Direct current (DC) is a type of electric current that flows in one direction only, producing a chemical reaction.

    Anaphoresis

    • Anaphoresis is a process that uses galvanic current to force substances into tissues.
    • In anaphoresis, the galvanic current flows from the negative pole towards the positive pole.
    • This process is used to introduce substances into tissues.
