Question

Write a C++ program that creates the following eight two dimensional random number vector: (a) the voltage vector V[][] contains n X m voltages between 100 and 1000 Volts, (where n.= #rows, m=# columns) (b) the current vector I[][] contains nXm currents between 10 and 50 Amps, (c) the phase vector PH[][] contains nXm phase angles between 0 and 45 degrees (d) The power vector (units of Watts) is given by: P[][] = V[][]*I[]*cos(PH[][]*M_P1/180); (e) The reaction vector (units of VARs) is given by: Q[][] = V[][]*[][]sin(PH[][]*M_P/180); (f) The Bill vector (units of dollars) is given by Cin >> rate; Bill[][] = rate*V[][]*|[][]; where rate is the cost of electricity per kilowatt-hour (see instructor for rate) entered by user (g) Finally, the user will enter a desired power factor (see instructor for this value); and your program will calculate the shunt capacitor required to create the new desired power factor, and the corresponding reduced power bill. Cin>> PF; C[][] = (Q[][] - p[][]*tan(acos(PF))/(377^*pow(V[][],2); New_bill [][] = squareroot (pow(P[][],2) + (Q[][] - P[][]*tan(acos(PF)))* (Q[][]- P[][]*tan(acos(PF)))); (Q[][] P[][] tan(acos(PF)))); int seed = time(NULL); srand(seed);
