    What is the Right Hand Grip Rule

    A rule that allows you to find the direction of a magnetic field around a current-carrying wire - by curling your four fingers into a circle and leaving your thumb outstretched, you can figure out which direction the current is flowing or the magnetic field is moving

  • 2

    Which Quantities are represented with the Right Hand Grip Rule

    Thumb represents direction of current, Other fingers represent direction of magnetic field

  • 3

    How does Alternating Current flow

    It oscillates in the shape of a sine wave

  • 4

    What is the Peak to Peak Value of Alternating Current

    Double the maximum positive value for current

  • 5

    Root Mean Squared Current, I_rms (Amps, A) =

    Peak Current, I⁰ (Amps) / √2

  • 6

    What is an Oscilloscope

    A device used to measure the amplitude and period of an alternating current

  • 7

    Which quantities are placed on the axes of an Oscilloscope

    y axis - potential difference function, x axis - time function

  • 8

    Low Pitched sounds have...

    Longer period / lower frequency

  • 9

    Loud Sounds have...

    Higher amplitude

  • 10

    Period (from Oscilloscope), T (seconds, s) =

    Total time (seconds, s ) / Number of Wavelengths

  • 11

    What is the Root Mean Square Value

    The effective output of current or voltage - average of the squares of every current/voltage value
