The figure shows an electric circuit which contains a double switch labelled by S. When the switch is in the position 11' the ammeter reads I = 6 A , and when the switch is in position 22' the reading is I1 =3 A. What is the reading on the ammeter when the switch is in position 33'? The electromotive forces E of the two batteries are equal, their internal resistances and the internal resistance of the ammeter are negligible.
