The maximum voltage would be across an infinite impedance (though for AC, a mismatched output impedance can create higher standing-wave voltage). The maximum current would be across a short circuit, i.e., 0 Ω, represented by the 1 Ω resistor, since one cannot measure voltage across a short circuit (again, with the caveat one could measure it ...
Open Circuit and Short Circuit
The open circuit voltage is the voltage difference measured between two terminals when no current is drawn or supplied. The short circuit current is the current that flows when the terminals are forced to have zero voltage difference. We''ll use these two values in Thevenin Equivalent and Norton Equivalent Circuits.
