Question 1:

Given a capacitor C = 0.5 /F and an inductor _ = 18 ml, find the frequency at which: a) XL = XC; Hz bj X_ = 5Xc: Hz c) Xo = 5XL HzA 116 /F capacitor is connected to a source that operates at 40 Hz with a peak potential difference of 14 V. Find: a) the peak current; A b) the current when the potential difference has its peak value; A c) the current when the potential difference has one-half the (positive) peak value (there are two answers, list them in increasing order); A A Hint, there are two possible angles within 0-2 * when you try to find time by using arcsin function. d) the instantaneous power delivered to the capacitor at 5 ms. WAn ideal inductor L = 90 mH is connected to a source whose peak potential difference is 65 V. a) If the frequency is 70 Hz, what is the current at 2 ms? What is the instantaneous power delivered to the inductor at this time? A W b) At what frequency would the peak current be 2.6 A? Hz
