  2. Although E is the answer they are looking for, E is much more commonly used for the electric field strength which is Volts per meter.
    The question is poorly written.

  3. I guess the context of the subject, the question and its choices would indicate that the class is in electricity or electronics, and not physics.

    Not much call for Electric Field strength in appliance repair... :-)
