Hello. I am currently trying to evaluate just how much power the external RC circuitry of a 555 timer uses over 1 cycle. Whilst the capacitor is charging the current falls exponentially. Naturally the voltage also falls through the resistors but this is couteracted by the rise in voltage of the capacitor as it charges. Basically what im trying to find out is whether there is a way to get an average current reading between 1/3Vcc and 2/3Vcc using the equation (4.5/101000 ⋅ e^(- x/0.4747) (4.5 = Vcc) (101000 is the total resistance in Ohms) (0.4747 is the RC time constant) Would the median value suffice?
