Very basic question: V = I*R
But consider a voltage source which can only provide 1 Amp of current. It is connected across a 1 ohm resistor. If we increase the voltage of the sourse above 1 Volt...what will be the potential across the terminals of the Resistor?
My understanding is that if we connect a voltmeter across the resistor, It will show 1 volt even if the voltage source is providing 2 V. The missing 1 volt drops across the internal output resistance of the Voltage source?
