19 A Resistance R And A Capacitor C Are Connected Via A Switch S To A Voltage Source Uo In The Beginning The Capacitor 1 (31.27 KiB) Viewed 42 times

19. A resistance R and a capacitor C are connected via a switch S to a voltage source Uo. In the beginning the capacitor is uncharged and at time t = 0s the switch is closed. By closing the circuit a current I = 1 mA starts to flow, and after a time t = 20 s, a voltage U. = 50 V is measured directly at the capacitor (see figure 1). How big is the resistance R and the capacitance C? Start with equation (55) of the lecture notes and give a derivation of eq. (56), before calculating the R and C values. U R Fig. 2
