Question

A 270​-kilo-ohm ​[kΩ​] resistor and a 0.4-microfarad ​[μ​F] capacitor rated at 210 volts​ [V] are connected in​ series, meaning that all of the current through the resistor enters the capacitor. ​

(a) Assuming that the capacitor is initially fully discharged and that a constant voltage of 5 volts​ [V] is maintained across the​ resistor, how​ long, in units of seconds​ [s], can this circuit operate before the voltage rating of the capacitor is​ exceeded?

The circuit can operate for _ s. ​(Round your answer to one decimal​ place.)
