The last question here, did he get part 2 wrong?
Isnt the resistor R meant to have changed its resistance, because it now has 3.6v rathher than 2v like it did in Q1.
If so, how would I work out this new resistance in R for Q2
Isn't a resistor in a potential divider meant to get a different resistance, if the voltage changes?
