In capacitive circuit current leads or lags
Web(3A2-C10-27) In a purely capacitive AC circuit the current: Select one: A. Leads the voltage by 90 degrees. B. Lags voltage by 90 degrees. C. Is out of phase by 45 degrees. D. Can … WebØ In case of resistance, voltage and current are in phase, so, VR will along current phasor. Ø In case of capacitance, current leads voltage 900 i.e. voltage lags by 900. so, Vc is shown downwards (i.e.) lagging current by 900 Ø The supply voltage being vector sum of these two voltages Vc and VR obtained by completing parallelogram

Did you know?
WebWhat does it mean when voltage leads current? It is customary to use the angle by which the voltage leads the current. This leads to a positive phase for inductive circuits since current lags the voltage in an inductive circuit. The phase is negative for a capacitive circuit since the current leads the voltage. WebJan 21, 2013 · In the beginning, the voltage rapidly increases and a current I = (VIN - VC)/R flows from the input source through the resistor and enters the capacitor; the output voltage begins increasing lazy. After some time, the input voltage approaches the sine peak and then begins decreasing.
