    Study Notes

    Time-of-Use (TOU) Rate

    • Rewards users for reducing power consumption during peak demand periods
    • Offers a lower rate for the remainder of the year

    Electricity Basics

    • Insulator: a material that resists the flow of electricity
    • Conductor: a material that carries electrical current with minimal resistance
    • Semiconductor: a material that is neither a good conductor nor a good insulator
    • Voltage: potential difference between two points
    • Amperage: flow of electric charge
    • Resistance: opposition to the flow of electric charge
    • Power: the rate of energy consumption
    • Energy: the total amount of work done

    Electric Circuits

    • Three components: voltage source, conductor, and load
    • Open circuit: a circuit with a broken path
    • Closed circuit: a circuit with a complete path
    • Short circuit: a circuit with an unintended path
    • Overcurrent protection: used to prevent excessive current flow
    • Control device: used to regulate the flow of electricity

    Series and Parallel Circuits

    • Series circuit: components connected one after the other
    • Parallel circuit: components connected between the same two points
    • Series circuit characteristics: same current, voltage divided between components
    • Parallel circuit characteristics: same voltage, current divided between components

    Magnetism and Electricity

    • Magnetism and electricity are related and can interact with each other

    AC and DC

    • DC: direct current, flows in one direction
    • AC: alternating current, flows in one direction and then reverses
    • Single-phase AC: one live wire and one neutral wire
    • Three-phase AC: three live wires and one neutral wire

    Transformers

    • A device that changes the voltage of an alternating current
    • Used to increase or decrease voltage

    Power Factor

    • The ratio of real power to apparent power
    • Power factor correction: used to improve the power factor of a circuit

    Demand and Load

    • Demand: the maximum amount of power required by a customer
    • Load: the amount of power actually used by a customer
    • Demand limiting: reducing the maximum power required
    • Load shedding: reducing the amount of power used

    Electricity Pricing

    • Energy charge: based on the amount of energy consumed
    • Demand charge: based on the maximum power required
    • Time-of-use (TOU) rates: charges vary based on the time of day and day of the week
