    A. An Ammeter.

    It is a device used to measure the electric current flowing through any circuit.

    D. E

    Along with E, V is also commonly used as a symbol for voltage.

    First question:

    The magnitude of current flowing in a circuit is described in

    units of Amperes. The device used to measure it is an Ampmeter,

    or Ammeter.

    Second question:

    This question is so absurd that it should not be dignified with an

    answer. Although 'E' is often used as the symbol for Electromotive

    force, potential difference, and voltage, there's certainly no rule.

    Anyone is free to use 'M', 'Q', 'Θ', or 'Щ' to denote voltage when

    they write electrical formulas, just as long as they make sure to

    explain the meaning of whatever symbols they use.
