The figure shows an electric circuit which contains a double switch labelled R, by S. When the switch is in the position 11' the 03 ammeter reads I, = 6 A , and when the switch is in position 22' the reading is I11=3 A. What is E the reading on the ammeter when the switch is in N R, R, position 33'? The electromotive forces E of the 03' two batteries are equal, their internal resistances and the internal resistance of the ammeter are negligible.
