    Study Notes

    Electric Current Fundamentals

    • The unit of electric current is the ampere (A), which is defined as one coulomb per second.
    • The direction of conventional current is from positive to negative, opposite to the flow of electrons.

    Voltage and Current Relationships

    • The relationship between voltage and current in a conductor is described by Ohm's Law, where current (I) is directly proportional to voltage (V) and inversely proportional to resistance (R), I = V/R.

    Resistors in Electric Circuits

    • The function of a resistor in an electric circuit is to reduce the voltage and current in the circuit by converting some of the energy into heat.

    Electric Circuit Pathways

    • The term for the path through which electric current flows is a circuit.
