WebMar 12, 2024 · You might have heard that one of the simplest ways to discharge the capacitor is by shorting its terminals, using a screwdriver or pliers. Actually, most technicians would place either pliers or a screwdriver between the two terminals of the capacitor and the work is done. WebSep 29, 2012 · From above, we see that capacitors do not discharge at a linear rate through resistors. When you do the math for a capacitor discharge, you get an exponential decay curve: V(t) = V 0 e-t / RC. This curve starts at the initial capacitor voltage (V 0), and diminishes quickly at first. As time goes on, the slope becomes less and less while the ...
