Hi - At @02:20 in your drawing you have connected your DVM to the wrong polarity's?.
With no load connected V out and V would be 20V with respect to 20R + 16R to 20V NEG making the Circuit. How ever the internal 20V load current is V/R = A = 20 / 100 = 0.2A

@5:16 You would know which is which because 1 is 20V o/p and the other is 16V o/p ?.

I know it's been 10 months, but please help me understand.
at 4:44, you put the 20 ohms and 80 ohm resistors as parallel.

I assume you used the parallel resistor formula, Rt = 1/R1+1/R2+1/Rn ?

wouldn't the total resistance for those two in parallel be:
1/20 + 1/80 = Rt = 1/16 or 0.0625?
But instead, you said it was 16 ohms.

What mistake am I making here?
