Question

Which of the following staiemeots is not true? Impedance of a resistor is equal to the value of its resistance in ohms impedance of an inductor is equal to jomegaL ohms Impedance values are phasor values and have frequency domain characteristics None of the above statements are true Which of the following statements is true about inductors and capacitors. Both are active devices; The voltage leads the current by 90 degrees in an inductor and the voltage leads the current by 90 degrees in a capacitor The current leads the voltage by 90 degrees in an inductor and th current leads the voltage by 90 degrees in a capacitor None of the above statements are true

Explanation / Answer

4. D is answer.

impedance values dont have frequency domain characteristics.

5. D

L and C are passive elements

voltage leads curret by an angle 900 in case of inductor

current leads voltage by an angle 900 in case of capacitor that is voltage lags behind current by 900 in case of capacitor
