2. In the figure below the current is measured with the ammeter at the bottom of the circuit. When the switch is opened, the reading on the ammeter (does not change, increases, or decreases.)
Homework Answers
When the switch is opened, the ammeter reading will decrease.
Beacuse, when the switch is open, the resistance \(R_{1}\) and \(R_{2}\) will be in series connection. So, the current flow will be less than before, i.e. ammeter reading will decrease.

Ammeter and Resistance
A circuit you're building needs an ammeter that goes from 0 mA to a full-scale reading of 40.0 mA. Unfortunately, the only ammeter in the storeroom goes from 0 μAto a full-scale reading of only 500 μA. Fortunately, you can make this ammeter work by putting it in a measuring circuit, as shown in the figure. This lets acertain fraction of the current pass through the meter; knowing this value, you can deduce the total current. Assume that the ammeter...
In the circuit in (Figure 1) the capacitors are all initially uncharged, the battery has no internal resistance, and the ammeter is idealized.
