To find the internal resistance of the voltage source channels, its just 30V/3A = 10Ohms and 5V/3A = 1.66Ohms. Is it correct? Eh. No. If that were the internal resistance, then a load of 3A would cause the output voltage to drop drastically. Ideal voltage sources have zero internal resistance - the current drawn is solely due to the external load.
The power dissipated by the internal resistance, represents the heat generated in the power supply. This is illustrated in the animation below. The terminal voltage (V) is equal to the e.m.f. voltage (E), minus the internal voltage drop (Ir). (using ohms law: internal voltage drop = current (I) x internal resistance (r)).
However, it can be calculated using the load regulation specification. For example, if the load regulation is specified at 2.75 mV when the current changes by 30 A (the amount of current change when the load changes from no load to rated load), the internal resistance is: 2.75 mV/30 A = 0.09166 milliohm (mΩ) = approx. 0.1 mΩ.
One way of doing this is by representing the power supply as a perfect voltage source, (an e.m.f.) in series with an internal resistance. When this power supply model is applied to an external circuit, then the circuit current also flows through the internal resistance.
