Very quick and informative video. Much appreciated.

Very, very long winded to say:
=> [voltage (no load) minus the voltage (under load)] divided by the current (under load).
=>[5V-3.6V]/0.3A=4.7Ohm. Short, easy, simple.

I'm enjoying these videos. Do you have worksheets for leaners?

does it matter in what order the components are connected?
