Question

Weknow that the formula relaing instantaneous cuent and voltage in a capacitor is this: de oit Knowing this, we can detemine thatif the capacitor voltagasinewave then the indu ctor ltage will be a cosine wave, as showin the diagrambelow: TIme How uch phase shift (in degres) is there beeen the current and voltage wavefoms? Which waveform is ading and which wavefomis lg Sdect the on bestanswer from the choices Eiven below) Phase shift is 90°, with the capacitor current leading the capacitor voltage (by 90°) Phase shift is 90°, with the capacitor current lagging the capacitor voltage (by 90°) Phase shift is 45°, with the capacitor current leading the capacitor voltage (by 90°) Phase shift is 45°, with the capacitor current lagging the capacitor voltage (by 90°) Ob. C. d. e. Phase shift is 0°, with the capacitor current in phase with the capacitor voltage

Explanation / Answer

vc = esin(wt)

ic = (e/c) sin(wt+90)
