In practice, capacitors deviate from the ideal capacitor equation in several aspects. Some of these, such as leakage current and parasitic effects are linear, or can be analyzed as nearly linear, and can be accounted for by adding virtual components to form an equivalent circuit. The usual methods of network analysis can then be applied. In other cases, such as with breakdown voltage, the effec…

reverse polarity

$begingroup$ While your polarized capacitor is unlikely to have problems with a small (<1V) reverse bias, you can eliminate this reverse bias entirely by putting a diode (1N914 for example) in series with the collector of T1.
