I am confused on a textbook I have. It suggests that if I know the frequency of a circuit and the required capacitive reactance, that I use the same formula to calculate capacative reactance but use instead the capacitive reactance instead of the capacitance. For instance, the formula for capacitive reactance is 1/2*pi*f*c. If I need 33.3 ohms of reactance at 60 hz, the book says I should calculate it as C=1/6.28*60*33.3. I was never taught to swap the ohms in the formula and don't see how that would work. I had thought the correct way to calculate this would be the equation 33.3 = 1/6.28*60*C. What am I missing?
