Hi there,
okay my Question is on discharging capacitors.
the equation for instantanious voltage of a capacitor whilst dischargeing is : v=Vi*e^-t/R*C
However I am not sure how to find the time for a capacitor to completely discharge to zero volts.
When I transpose for t
t=-(R*C)*ln(v/Vi)
and input v as zero (cap has completely discharge) we get an undefined answear.
I havnt studied calculus and am not familiar with the concept of limits.
how would I go about finding the precise time for a capacitor to discharge without using a normalised universal time constant curve to estimate the answear.
thanks in advance
