@ericgibbs , sorry Eric, my response was not aimed at you, it was for the TS. I think we both responded at the same time.I know that , I am trying to determine the TS's 'learning' level'
Hi,Hello All,
I have a 1.8V circuitry with two parallel capacitors and please let me know how can I setup or find out the impedance across the capacitor C420.

At DC the impedance across an ideal capacitor is infinite. That is, it completely blocks DC current. The impedance of two ideal capacitors in parallel is still infinite. For any finite frequency f, the reactance of the capacitor is given by:Hello All,

Do tell.Hello again,
Ok i tried it and you don't even have to know the frequency to calculate the impedance of C420.
That's a good hint.If Vcc is a SPICE voltage source, then the impedance will be zero.
Hi,If Vcc is a SPICE voltage source, then the impedance will be zero.
Hi Bob,Do tell.
Hi Bob,I assume you are reading the @4A as an actual current reading. Then yes, you can calculate the impedance without knowing a frequency, but that is not the way I read it.
Hi Bob,Oh, I know what you did. I just am not sure about your assumptions. I worry that the poster has not given us everything the prof gave them.
