hi

Maybe this question is stupid and simple, but I'm stuck on it.

in the below pic, how can i calculate impedance between the two points a and b?

again, i think it is a stupid question, but i trapped in it for 1 hour.

thanks

hi again

i wanted a formula that express equal impedance in c's and r's and how this formula is gained.

thanks
