    Ampere- symbol I to represent the current.

    Omega (Ω)- Greek alphabet that symbols resistance.

    Voltage- the force that causes current to flow in a circuit.


    4. Lesson Proper

    Whenever you turn on your television or computer or flip


    a light switch, you have completed an electrical circuit.
    We use the word 'circuit' when we talk about something
    that goes around and starts and stops in the same place;
    for example, you might run a circuit, or a lap, around a
    track. To have a complete electrical circuit, you must
    have a cell that provides the electrical current, a
    conductor to carry the current, and a resistor to use the
    current. More than one cell put together is called a
    battery. The conductors can be anything that allows
    electricity to pass through it easily; usually these are
    wires.
    There are several different kinds of electrical circuits.
    One of these is called a series circuit. The word 'series'
    means a number of things that follow each other; for
    example, you might read a series of books or watch a
    television series with many episodes.

    Series Circuit:

     Type of circuit where loads are connected end to end


    along the path in a single closed loop. In series
    circuit, if one bulb is busted, all bulb goes off.
     The current through series component is equal
    because there is only one path for electrons to flow in
    a series circuit, and because free electrons flow
    through conductors.

    Ohm’s law states the relationship between voltage (V),


    current (I), and resistance (R). The equation is simplified
    as V = I x R. This law explains the how the most
    important concepts of electricity relate to each other. It is
    beneficial to us because it helps us calculate currents
    and voltages in circuits.
    The following rules apply to a series circuit:
    A. The total resistance in a series circuit is computed by
    adding all resistances.

    Formula: Rt= R1 + R2 + R3… (formula depends on the


    number of resistors)
    Solution: Rt= 100Ω + 200Ω + 300Ω
    Rt= 600Ω

    B. Computing the total voltage in series circuit:


    Example: In a toy car, 3 batteries were connected end to
    end or in series to supply the motor. Each battery has the
    voltage of 2.5 volts. Find the total voltage.

    The sum of all individual voltages will give the total


    voltage.
    Formula: Vt= V1 + V2 + V3… (formula depend on the
    number of battery)
    Solution: Vt= 2.5V + 2.5V + 2.5V= 7.5V

    C. Computing the total current in a series circuit.

    The total current in series circuit is equal to the flow of


    current in each loads.
    Formula: It= I1 = I2 = 13
    Solution: It= 0.5A = 0.5A = 0.5A

    Safety Precautions:
     Avoid horse playing
     For girls, tie your hair
     Wear your Personal Protective
    Equipment (PPE)
     Always use equipment/tools safely
    and properly

    “To avoid accidents and to finish

    laboratory?”
    Step-by-step Procedure:
    1. Gather the necessary materials- to
    build a simple circuit, you will need a
    power source (battery), insulated
    wires, a light bulb and a light bulb
    holder, and a switch.
    2. Strip the ends of the insulated
    wires- in order for your circuit to work
    properly, the wires needed to be
    totally exposed so you must strip at
    least 2.5cm at the end of the wires.
    3. Fasten one end of the wire to the
    metal screw of the bulb holder,
    switch, and battery.
    4. Connect the wires of your
    components. (Follow the schematic
    diagram of series circuit)
    5. Test your circuit- if the bulb doesn’t
    light, check to make sure the wires
    are touching the ends of the battery
    and in contact with the metal of the
    screws.
