The circuit shown includes an $80\text{ V}$ battery connected to four $100 \ \Omega $ resistors, labeled ${ R }_{ 1 },{ R }_{ 2 },{ R }_{ 3 }$ and ${ R }_{ 4 }$. Resistor $R_{ 4 }$ is connected in parallel with a $5\mu F$ capacitor.

An ammeter, $A$, is installed to measure the current through flowing into the capacitor.

The switch has been closed for a very long time.

What is the current measured by the ammeter?


$0.00\text{ amps}$


$0.80\text{ amps}$


$0.27\text{ amps}$


$0.20\text{ amps}$
