I = E/squareroot R^2 + (2pi FL - 1/2pi FC)^2 I = current in Amps E = Electromotive Force in Volts R = Resistance in Ohms F = Frequency of the Current in Hertz L = Inductance in Henrys C = Capacitance in Farads Where, F is frequency (measured in Hz), E is EMF (Voltage) and I is current (measured in Amps). A. Write a C++ program which does the following: a) Declares Pl as a constant and sets its value to 3.14159, b) Declares all other variables described above as local variables. c) Prompts for the input of (and inputs) resistance frequency, capacitance, inductance and EMF. d) Calculates and displays the current. B. Test your program with this test data: f = 200 Hz R = 15 Ohms C = 0.0001 (100 infinity F) L = 0.01476 (14.76mH) E = 15 V Answer: I = 0.816918A (calculated) C. Using your program, try different frequencies and try to find the resonant frequency (where the current is at a maximum. F_r = 1/(2.PI. squareroot (L.C)) At resonance, the inductor and capacitor will cancel each other out, so the max current should be I = E/R = 15/15 = 1.0 Amps
