The −j phase indicates that the AC voltage V lags the AC current by 90° unlike the resistor where both the V and I are in phase.Impedance decreases with increasing capacitance and increasing frequency. This implies that a higher-frequency signal or a larger capacitor results in a lower ...
As can be seen from the graph, the voltage of a capacitor lags behind the capacitor current. Alternatively, it can be said that the capacitor current leads capacitor voltage by 90 degrees. In order to represent this fact using complex numbers, the following equation is used for the capacitor...

but these two quantities are not identical. Reactance is expressed as an ordinary number with the unit ohms, whereas the impedance of a capacitor is the reactance multiplied by -j, i.e., Z = -jX. The -j term accounts for the 90-degree phase shift between voltage and current that occurs...
If we compare the Eq.29, and Eq.30 we find that the current I and the voltage U have the same frequency, and I lags behind U byπ/2. The resultant curves can be studies in the following diagram: C This shows the contrasting relationship between capacitor and inductor. For an inductor...
PURPOSE:To improve the trolling performance of the ignitor by a method wherein the output voltage of a generator is detected and when this valve exceeds an intended valve, the phase of the effective part of the current passing through the switching element of a pulser is delayed to lag the ...
Most heavy electrical loads have a lagging power factor (Load current lags the load voltage). A capacitor draws a current that leads the load voltage, thus cancelling out the lagging current of the un corrected load.. Reactions: sohail qureshi S sohail qureshi Points: 2 ...
Irunis thecurrentflowing through the main or running winding, Istartis the current flowing in starting winding, VTis the supply voltage. In a highly resistive winding, the current aligns closely with the voltage. Conversely, in a highly inductive winding, the current significantly lags behind the...
