Hello all, i need help figuring out my calculations. I was asked to calculate the capacitive reactance of a circuit with AC current. The capacitor has a value of 470nF. For 6 different Hz values (1,10,100,..,100k) i calculated the theoretical capacitive reactance. 1hz => 338799 ohms , 10hz => 33879,93 ohms and so on. I used 1 / 6.28 * Hz * 470 * 10 ^ -9
Now i made the circuit in the lab, calculated the Vc of the capacitor and the Ic and did Xc ( measured ) = Vc/Ic =>
For 1hz =>(too low of a frequency for a calculation) ,10 hz => 12.5 ohms, 100hz => 3.04 ohms and so on
Did i so something wrong? If not, what can i attribute to these staggering differences?
