1. The problem statement, all variables and given/known data find the rms current delievered by the 45v (rms) power supply when a) the frequency is very large and b) the frequency is very small. answer: a) 225mA, b) 450mA http://yfrog.com/jucurrentqg http://img714.imageshack.us/img714/1592/currentq.gif [Broken] Uploaded with ImageShack.us 2. Relevant equations w= angular velocity (supposed to be omega) L= inductor C= capacitor j= complex coefficent = sqrt(-1) Zl= resistance of inductor Zc= resistance of capacitor Ztot= total resistance R= resistance of resistor P= Power Xl=wL Xc=1/wc Zl=j*Xl Zc=-j*Xc Ztot= R + Zl + Zc = R + j(Xl-Xc) 3. The attempt at a solution with frequency just being high, how am I supposed to get these exact numbers without letters/symbol for I? o.o I tried the calculation and omega did not cancel out either.
