Objective:
1. To measure the voltages of a circuit in different frequency.
2. To plot voltages of R-C and R-L series circuit versus frequency.
3. To plot the input impedance of a circuit versus frequency.
Equipment
:
Multisim Application
Theory:
The impedance made by the capacitor/inductor depends on the frequency. Basically: as the
frequency increases, the overall impedance of the circuit decreases(with the capacitor). Now for
the inductor the overall impedance of the circuit increases.
The voltage drop for the capacitor decreases while the inductor increases.
