Homework Statement
Homework Equations
w = 10^5 rad/s
Z(L)= jwL
Z(C) = -j/wC
Z(eq)= ??
Zeq(rectangular form) = a+jb
Zeq(polar form)= p<(theta)
p = sqrt(a^2 + b^2)
theta = arctan(b/a)
The Attempt at a Solution
i calculated the impedences across the inductor/resistors:
across 0.5uF capacitor: -j/wC = -j/(10^5)(0.5 x 10^-6) = -j/0.05 = -20j
across 0.1mH inductor: jwL = j(10^5)(0.1x10^-3)= 10j
across 10uF capacitor: -j/wC = -j/(10^5)(10x10^-6)= -j
still not sure what to do with the resistances. would i have to find R(eq)? if i do this by 10+ 10||10 i get 15ohms.
to get to rectangular form before converting to polar form would be:
R+jX, where i think R would be the R(eq) and X would be the equivalent impedence across both inductors and capacitors? how would i find this by adding them together?
