A 3-phase ring main ABCD fed at A at 11 kV supplies balanced loads of 50 A at 0.8 p.f. lagging at B, 120 A at unity p.f. at C and 70 A at 0.866 lagging at D, the load currents being referred to the supply voltage at A. The impedances of the various sections are :
Section AB = (1 + j 0.6) Ω ; Section BC = (1.2 + j 0.9) Ω
Section CD = (0.8 + j 0.5) Ω ; Section DA = (3 + j 2)Ω
Calculate the currents in various sections and station bus-bar voltages at B, C and D.
The rectangular shaped current pulse is applied to 0.5microFarad capacitor.The initial voltege on the capacitor is a 20V drop in the reference direction of the current. Assume the passive sign convention. Derive the expression for the capacitor vo..
Loop antennas are very common and are often used by amateur radio sites. In fact, the figure on the right is provided as an example what one may find when searching for loop antennas on the web.
Using the time independent one dimensional Schrodinger equation, find the expression of the allowed energy levels for an electron in infinite potential well of width Δz= L (i.e. solve the differential equation and apply B.C. to obtain En)
