    Thevenin reduction of network for fault analysis trouble.

    I have just realized i have not converted from cart to pol when calculating equivalent impedance. doh, i think this may have been the problem

    I Capacitive Reactance: Opposing Voltage Changes & Impedance

    Hi Folks, I am reading some text about capacitive reactance that reads 'so we know that capacitors oppose changes in voltage' would this be the supply voltage or the voltage in the capacitor? I am struggling to see how the change is opposed surely the quoted statement would infer increasing...

    Simplifying a fraction (block reduction, control)

    I was thinking why two of the 4's come out on the bottom line and only one on the top. Is this because the two 4's on the bottom line are from different expresions?
