terminal. Option A is incorrect because that describes electron flow. Correct Answer: B Ammeters must be connected in

a) ( \frac1R_p = \frac16 + \frac13 = \frac16 + \frac26 = \frac36 \Rightarrow R_p = 2 , \Omega ) b) ( I_\texttotal = \frac122 = 6 , \textA ) c) ( I_6\Omega = \frac126 = 2 , \textA, \quad I_3\Omega = \frac123 = 4 , \textA )
