An ideal voltage source doesn't have "resistance" per se, because it does not obey Ohm's law. But you can define its impedance, Z = Δ V / Δ I, which, like resistance, is measured in Ohms. The impedance of an ideal voltage source is zero, because no matter what happens with the … small space washing machine
