B) 180 and 135 V
C) 160 and 80 V
D) 140 and 20 V
Correct Answer: B
Solution :
Decay equation of potential difference across capacitor \[y=5\sin \frac{\pi x}{3}\cos 40\pi t\] or \[5\times {{10}^{14}}\] or \[\overset{0}{\mathop{A}}\,\] ??..(i) For t =2s \[\overset{0}{\mathop{A}}\,\] ??.(ii) \[\overset{0}{\mathop{A}}\,\] [from Eq. (i)] Fort =3s \[\overset{0}{\mathop{A}}\,\] \[\mu \] ?...(iii) \[d\frac{20}{3}\] [from Eq.(i)]You need to login to perform this action.
