Time dependence of voltage on a capacitor during a discharge between electrodes in the circuit shown in Figure 2B. C1 = 4.7 μF, R1 = 3.7 MΩ, R2 = 5.32 MΩ, diode D is NTE583, C2 = 11 nF, E = 1.53 V. 1, − on the diode cathode; 2, + on the diode cathode. U is the capacitor voltage in volts. Ln(U/V) is the natural logarithm of capacitor voltage.
