II.A The concept of circuit loading Fig 1 shows a voltage source, whose nominal output is Vin. When connecting this source to an external circuit, a user would expect the voltage across the terminals a and b to be Vin. But, because any real voltage source has an intrinsic internal resistance (rsource), by attaching an external load resistance RL , the voltage across the terminals a and b will b eless than V in. The difference between Vab and Vin is more dramatic when RL is less than or even comparable to the internal resistance rsource; this is illustrated through expression (1) and the corresponding graph in Fig 1.
