Problem
A signal generator has an internal source resistance of 50Ω and its front-panel display assumes an open-circuit load. It is set to display 2.00V and then connected to a load of 75Ω.
((a)) Draw the generator as an ideal voltage source in series with its 50Ω output resistance, feeding the 75Ω load, and state what voltage the displayed 2.00V represents.
((b)) Calculate the voltage actually delivered across the 75Ω load.
