Which of the following equations is the correct definition of the reactance of an indicator L?
Reactance = (Amplitude of voltage) \(\div\) (Amplitude of current)
Reactance = (Amplitude of voltage) x (Amplitude of current)
Reactance = (Amplitude of current)\(^2\) \(\div\) (Amplitude of voltage)
Reactance = (Amplitude of current)\(^2\) \(\div\) (Amplitude of voltage)\(\frac{1}{2}\)
Spiegazione
Reactance is the value of an indicator or a capacitor in ohms
