The figure аbоve shоws а 10 V bаttery cоnnected in a circuit with two resistors, a parallel plate capacitor of capacitance , and three ammeters. The circuit has been connected for a long time. Let be the current in ammeter . Which of the following correctly ranks the currents in the 3 ammeters? A rectangular circuit contains a 10 volt battery on the left side. Along the top branch is an ammeter labeled A sub 1 followed by a 50 ohm resistor. A junction splits to the right and downward. The downward branch passes through capacitor C and an ammeter labeled A sub 2. The right branch passes through ammeter A sub 3 then turn downward through a 100 ohm resistor before turning left to form the bottom branch. The bottom branch completes the loop back to the battery.
