Question 1.1: RLC Circuit Calculations Given: Resistance, R = 13 \, Inductive Reactance, X_L = 47.13 \, (given in , so it's reactance) Capacitance, C = 100 \, F = 100 × 10^-6 \, F Supply Voltage, V_supply = 100 \, V Frequency, f = 50 \, Hz Step 1: Calculate Capacitive Reactance (X_C) X_C = (1)/(2 f C) X_C = (1)/(2 (50 \, Hz)) (100 × 10^-6 \, F) X_C = (1)/(0.0314159) X_C ≈ 31.83 \, Step 2: Calculate Total Impedance (Z) Z = sqrt(R^2 + (X_L - X_C)^2) Z = sqrt((13 \, )^2 + (47.13 \, - 31.83 \, )^2) Z = sqrt(169 \, ^2 + (15.3 \, )^2) Z = sqrt(169 \, ^2 + 234.09 \, ^2) Z = sqrt(403.09 \, ^2) Z ≈ 20.08 \, 1.1.1 Draw the circuit diagram. A series RLC circuit consists of a resistor, an inductor, and a capacitor connected in series to an AC voltage source. ` R L C ---[ R ]---[ L ]---[ C ]--- | | +---( ~ )-----------+ AC Source ` 1.1.2 Calculate the total current flowing in the circuit. I = V_supplyZ I = 100 \, V20.08 \, I ≈ 4.98 \, A The total current flowing in the circuit is 4.98 A. 1.1.3 Calculate the voltage drop across the resistor. V_R = I · R V_R = (4.98 \, A) · (13 \, ) V_R ≈ 64.74 \, V The voltage drop across the resistor is 64.74 V. 1.1.4 Calculate the voltage drop across the inductor. V_L = I · X_L V_L = (4.98 \, A) · (47.13 \, ) V_L ≈ 234.71 \, V The voltage drop across the inductor is 234.71 V. 1.1.5 Calculate the voltage drop across the capacitor. V_C = I · X_C V_C = (4.98 \, A) · (31.83 \, ) V_C ≈ 158.52 \, V The voltage drop across the capacitor is 158.52 V. 1.1.6 Calculate the phase angle. = ((X_L - X_C)/(R)) = ((47.13 \, - 31.83 \, )/(13 \, )) = ((15.3 \, )/(13 \, )) = (1.1769) ≈ 49.64^ The phase angle is 49.64^. 1.1.7 Draw the phase diagram of the above circuit. The phase diagram (phasor diagram) shows the voltage phasors relative to the current. Since X_L > X_C, the circuit is inductive, and the total voltage leads the current. V_R is in phase with the current I. V_L leads the current I by 90^. V_C lags the current I by 90^. V_supply is the vector sum of V_R and (V_L - V_C). ` ^ V_L | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | |
