2nd experimental exercise. Read about Measuring the Impedance..

The Report should be handed in Friday 22nd of March.The Report should contain

-         Theory on the concept of Impedance, especially concerning the impedance of a capacitor and an inductor

-         Diagram of the measurement setup and an explanation of the measuring principle.

-         Phasor diagrams illustrating the relation between the current amplitude Î and the voltage amplitudes Û og V for the two cases.

-         The impedance of the capacitor, Z_C and the inductor Z_L is calculated from data. Modulus should be plottet as (log(ω),log(|Z|)) and the phase as (log(ω), φ_Z ).

-         The coil is not an ideal self inductor. Find the series resistance R_L  and investigate Z_L,pure  = Z_L,measured –R_L .

-         Discuss whether Z_L  and Z_C  follows the expected frequency dependencies og calculate the magnitude of C and L.
