Hello again, I am trying to knock out some challenge questions in my text (to prepare for my midterms) and I came across this question. A 10V, 2.5kHz, sine wave is applied to a series combination of a 0.01µF capacitor and a 10kΩ resistor. What would the total current be? The answer in the back of the book says 0.844mA I am not getting anything anywhere near that. Can someone please tell me where I am thinking incorrectly? Thanks. Here is my thought process. First, calculate the capacitive reactance: 1/2πfC = 1/(2πx2500x0.1x10^-6) = Xc = 6366.2Ω This is where I think I am going wrong. since the capacitor and the resistor are in series, so i added the capacitive reactance and resistance together: 6366.2 + 10,000 = 16,366.2Ω I then applied ohm's law to get 10/16366.2 = 0.611mA which is way off Using backwards design, I figured 10/0.844mA = 11,848Ω which means that in some way shape or form, my total resistance in the circuit should be 11848Ω I cannot figure out how to get my Xc of 6366.2Ω and resistor 10k to combine in a manner that would be 11848Ω Any insight would be great! Thanks!
