    An ideal voltage source has:
    Question

    An ideal voltage source has:

    A.

    terminal voltage in proportion to load

    B.

    open circuit voltage equal to the voltage on full load

    C.

    zero internal resistance

    D.

    terminal voltage in proportion to current

    Correct option is C


    An ideal voltage source has zero internal resistance. This means that it can supply or absorb any amount of current, and the current flowing through it is determined by the external circuit. 
    Explanation:
    · An ideal voltage source has zero internal resistance, so it can supply or absorb any amount of current. 
    · The current flowing through an ideal voltage source is determined by the external circuit. 
    · A practical voltage source is made up of an ideal voltage source in series with internal resistance. 
    · In a parallel circuit, the voltage across all the elements is the same. 
    · An element connected in parallel with an ideal voltage source is redundant and is equivalent to an ideal voltage source.
