Assignment:
Q1.) The current in a circuit is i = 2.00 cos 100t. Find the voltage across a 100-microfarad(uF) capacitor after 0.200 s, if the initial voltage is Zero (one microfarad(uF)=10 to the power of -6 F).
Q2.) Find the volume of the solid of revolution obtained by rotating the region bounded by y = cos x to the power 2, x=0, x = square root of (pi/2) and y = 0 about the y - axis.
Q3.) The voltage in a certain circuit is given by e(t) = E sin wt . Find the mean voltage over half a period.
Provide complete and step by step solution for the question and show calculations and use formulas.
