-Single Ended Floating signals are signals which are not electrically connected to ground.  The signal of interest appears between the two terminals of the signal source.
+Single Ended Floating signals which are not electrically connected to ground. The signal appears between the two terminals of the signal source. This signal can either be a voltage source or a current source.
-This signal can either be a voltage source or a current source.
+An ideal voltage source has a near zero internal impedance - a battery for example.  A pH electrode is a voltage source but this has a very high internal resistance. An accurate reading can only be obtianed with a measuring circuit whose own internal resistance is much higher than the source resistance of the source. Voltmeters therefore need to have a high internal reistance - ideally infinite.
-An ideal voltage source has zero internal impedance
+An ideal current Source has a near infinite internal impedance - a solar cell. In this case to measure the source current the measurment impedance should be very low.  Ammeters therefore need to have a low internal resistance - ideally zero.
