  2. Voltage source - Wikipedia

    en.wikipedia.org/wiki/Voltage_source

    The internal resistance of an ideal voltage source is zero; it is able to supply or absorb any amount of current. The current through an ideal voltage source is completely determined by the external circuit. When connected to an open circuit, there is zero current and thus zero power.

  3. Current source - Wikipedia

    en.wikipedia.org/wiki/Current_source

    An ideal voltage source loaded by an open circuit (i.e., an infinite impedance) will provide no current (and hence no power). But when the load resistance approaches zero (a short circuit), the current (and thus power) approach infinity. Such a theoretical device has a zero ohm output impedance in series with the source.

  6. Common-mode rejection ratio - Wikipedia

    en.wikipedia.org/wiki/Common-mode_rejection_ratio

    In electronics, the common mode rejection ratio (CMRR) of a differential amplifier (or other device) is a metric used to quantify the ability of the device to reject common-mode signals, i.e. those that appear simultaneously and in-phase on both inputs.
