A battery with negligible internal resistance is connected to a resistor network, an ammeter and a switch $S$, as illustrated. With $S$ open, the ammeter reading is $250\,\text{mA}$. With $S$ closed, what change occurs in the ammeter reading?
- A$1.07\,\text{A}$
- B$1.32\,\text{A}$
- C$190\,\text{mA}$
- D$440\,\text{mA}$
