Verify Series and Parallel Capacitance Formulas: Measure the equivalent capacitance (Ceq) for series and parallel combinations and compare the experimental values to the theoretical calculations.
- Study Frequency Response: Observe how the capacitive reactance (XC) and the resulting circuit current or voltage change as the input signal frequency (f) is varied.
Note that XC is inversely proportional to frequency (f) and capacitance (C).- Demonstrate Resonance (if including an inductor): If using an L-C-R circuit, find the resonant frequency (f0) where the capacitive reactance and inductive reactance (XL) cancel out, minimizing (series) or maximizing (parallel) the impedance.
🛠️ Required Equipment
Function Generator (or Signal Generator): To provide a variable-frequency AC voltage (usually sinusoidal).
Digital Multimeter (DMM) or Oscilloscope: To measure voltage (RMS/peak) across components and sometimes current. An oscilloscope is better for viewing the signal waveform and phase shifts.
