Sir please tell what is the phase angle between current and voltage when it pass through pure capacitance

1)60

2)90

3)180

4)0

and also tell how to find it through capacitance

Sir please tell what is the phase angle between current and voltage when it pass through pure capacitance 1)60 2)90 3)180 4)0 and also tell how to find it through capacitance

vikas askiitian expert · Answer

E = E o sinwt ..............................1 E o is the peak voltage E across capacitor = dq/c dq/c = E o sinwt differentiating this equation (1/c)(dq/dt) = E o wcoswt I = E o wc coswt ...................2 I = E o /(1/wc) {coswt} 1/wc = R c (capacitive reactance) I = E o wc {sin(pi/2 +wt)} .............3 [cos@ = sin(pi/2+@) ] comparing eq 1 & 3 we see that current leads the voltage by an angle of pi/2 therefore phase difference bw current & voltage across capacitor is 90 o ....... approve if u like my ans
