A 8000 u03a9 resistor is joined in series with a 10 u03bcf, Ask an Expert

Academics

A 8000 %u03A9 resistor is joined in series with a 10 %u03BCF capacitor. What is the capacitive time constant of this combination?

If a 18.0 volt battery is suddenly connected across this RC combination, how long will it take for the capacitor voltage to reach 17.0 volt?
