Using Multisim 14.2 to simulate a capacitor's charge cycle , I've noted that when the simulation starts for the first time, even if the SPST switch is OFF, the capacitor starts fully charged. Any idea?
Most (if not all) simulators "try and help out" by calculating all the steady-state DC conditions first then, the simulation is run so, your capacitor has already been forced into the steady-state situation.
In micro-cap there is a tick-box called "operating-point" and if I uncheck it, the simulation begins right from the very start without calculating steady-state DC conditions.
The same will be true of multisim but, I can't help you find that "checkbox" because, I don't use multisim.
