3. In a series RC circuit, the resistor has a value of 20.0 k , the capacitor has a capacitance of 10 nF, and they are connected to a 20.0 V source. (a) Determine the time constant t (b) The circuit it has been connected for a long period of time and at t=0 it is disconnected from the voltage, leaving only the capacitor and resistor connected in series. Determine the time it takes for the capacitor to discharge to 30% of its initial value.
3. En un circuito RC en serie el resistor tiene un valor de 20.0 ks2, el capacitor tiene una capacitancia de 10 nF y están conectados a una fuente de 20.0 V (a) Determine la constante de tiempo t. 2 puntos (b) El circuito ha estado conectado un largo periodo de tiempo y en t = 0 se desconecta del voltaje quedando solamente conectados el capacitor y el resistor en serie. Determine el tiempo que le toma al capacitor descargarse un 30% de su valor inicial. 8 puntos
