But, there are no ideal voltage sources, i.e., all real voltage sources have some maximum current delivered into a short circuit. This is modelled by placing a resistor in series with an ideal voltage source and this resistance is the "internal resistance" or "source resistance". Clearly, the maximum current from such a source is:
