Question

The 500 Hz Square Wave allows 10^-3 seconds for each RC combination to charge. How many time constants is this fo the four cases?

I was able to workout part a, but am having trouble with part b. I calculated the RC time constant for each case, but how do you figure out how many time constants are in each case?

part a) Calculate the RC time constant for each case. 10K & .01µF = 1.0*10^-4 10K & 0.1µF = 1.0*10^-3 100K & .01µF = 1.0*10^-3 100K & 0.1µF = 1.0*10^-2

part b) The 500 Hz Square Wave allows 10^-3 seconds for each RC combination to charge. How many time constants is this fo the four cases?

The 500 hz Square Wave allows 10K & .01µF = ______ 10K & 0.1µF = ______ 100K & .01µF = ______ 100K & 0.1µF = ______

Explanation / Answer

you are just suppose to divide given time by time constant to get the number of time constant

for the 1st case, time constant = 1*10^-4 s
number of time constant= 10^-3/(1*10^-4) = 10

for 2nd case:
number of time constant= 10^-3/(1*10^-3) = 1

for 3rd case:
number of time constant= 10^-3/(1*10^-3) = 1

for 4th case:
number of time constant= 10^-3/(1*10^-2) = 0.1
