LAB REPORT FOR MP11 EXPERIMENT: RLC Circuits and Resonance VI(1) R-C ℓ measured = 1.1x0.2mS L measured = 4.9x0.2mS Phase Difference is calculated by equation: Thus, ф = 80.8˚ R-L ℓ measured = 1.1x0.2mS L measured = 4.9x0.2mS Phase Difference is calculated by equation: Thus, ф = 80.8˚ Here the phase differences between R and C & R and L are expected. Both have same phase difference. VI(2) R-L-C V(3) Frequency Range covered 300Hz above and below resonant frequency in steps of 40Hz.

VI(3) R L =1.317K Quality factor for V(3) f for V(3) = 160Hz f R for V(3) = 1360 Thus, Q from graph = f R / f Thus Q=8.5 Now Q from Equation: Q= 2 f R L/R+ R L Therefore Q = 5.6 Quality factor for V(3) f for V(3) = 610Hz f R for V(3) = 7740Hz Thus, Q from graph = f R / f Thus Q=12.68 Now Q from Equation: Q= 2 f R L/R+ R L Therefore Q =32.05 New Question pearmeability = L / L where L is for inductor with iron core and L is for inductor without iron core. Now L is given by: Thus, L = 0.105 & L = 247.366 Thus, = 4.24e-4 Hm-1...
