Talk:A-level Physics (Advancing Physics)/Internal Resistance/Worked Solutions

Resistance Incorrect You've added up the resistance using 1/R but you have to flip it back again. the resitance listed on Q2 is 0.2 something ohms but it's actually 3 ohms.

UNITS!!!! Please be careful to include units in your solutions, you toilet monsters. Thefloogadooga (discuss • contribs) 10:04, 8 January 2013 (UTC)
