    1. The document describes an experiment on current and potential difference in series and parallel circuits. Tables are presented showing voltmeter and ammeter readings for circuits with different numbers of resistors/bulbs arranged in series and parallel. 2. Key conclusions are that resistors in series divide potential difference, keeping current constant, while more resistors in series decreases current; resistors in parallel divide current, keeping potential difference constant. 3. Whether using bulbs or resistors, the brightness/current is less for components in series compared to parallel.

    MEMORANDUM

    Experiment: Current and potential difference in series and parallel circuit.

    Step 2: Table 1
    Number of
    Voltmeter reading (V) Ammeter reading (A)
    bulbs/resistors
    1 ✔ ✔
    (2)

    Step 3: Table 2

    Number of
    bulbs/resistors in Voltmeter reading (V) Ammeter reading (A)
    series
    V1 V2 VT A1 A2 AT
    2
    ✔ ✔ ✔ ✔

    (4)

    1. The total current decreases as you add the resistor in series ✔ (1)

    Die totale stroomsterkte verminder soos daar nog ‘n weerstand in serie


    bygevoeg word.

    2. The total current stays the same amongst the two resistors. ✔ (1)

    Die totale stroomsterkte bly dieselfde tussen die twee weerstande.

    3. I1 = I2 = IT ✔ (1)

    4. Increase. ✔ Vermeerder (1)

    5. V1 + V2 = VT ✔ (1)

    Step 4: Table 3.

    Number of
    bulbs/resistors Voltmeter reading (V) Ammeter reading (A)
    in series
    V1 V2 V3 VT A1 A2 A3 AT

    ✔ ✔ ✔ ✔
    (4)

    6. The total current remains the same amongst the three resistors ✔ (1)

    Die totale stroomsterkte bly dieselfde tussen die drie weerstande

    7. I1 = I2 = I3 = IT ✔ (1)

    8. Stay the same✔ Bly dieselfde (1)


    9. V1 + V2 + V3 = VT ✔ (1)

    Step 6: Table 4

    Number of
    bulbs/resistors in Voltmeter reading (V) Ammeter reading (A)
    parallel
    V1 V2 VT A1 A2 AT
    2
    ✔ ✔ ✔ ✔
    (4)

    10. I1 + I2 = IT ✔✔ (2)

    11. Stay the same ✔ (1)

    Bly dieselfde

    12. V1 = V2 = VT ✔✔ (2)

    Conclusion:

    Resistors in series are potential difference dividers and current remains constant /
    the same. ✔

    The more resistors in series, the less current will be. ✔

    Resistors in parallel are current dividers and the potential difference remains
    constant / the same ✔

    (Also accept if bulbs were use: The more bulbs in series, the dimmer the light will be,
    the bulbs in parallel will be brighter than in series ✔)

    Weerstande is serie is potensiaal verskil verdelers en die stroomsterkte bly


    konstant / dieselfde. ✔

    Hoe meer weerstande in serie, hoe minder sal die stroomsterkte wees. ✔

    Weerstande in parallel is stroomsterkte verdelers en die potensiaal verskil by


    konstant / dieselfde ✔

    (Aanvaak ook wanneer gloeilampies gebruik is: Hoe meer gloeilampies in serie, hoe
    dowwer sal die gloeilampies wees, die gloeilampies in parallel brand helderder as in
    serie ✔)

    (max 2)

    GRAND TOTAL: 30
