AC Circuit Analysis Laboratory (Practical Course)

Explore the breadboard as a practical tool for DC circuit experiments, learn how power rails and nodes organize connections, and master series and parallel resistor layouts.

Learn to craft a formal, technically accurate lab report for the ac circuit analysis lab, covering title, abstract, methodology, equipment, figures, results, discussion, and references.

Analyze an RC circuit with a 5-volt source, 22 kΩ resistor, and 1000 μF capacitor to determine the capacitor voltage at the time constant and during charging.

Explore the RC circuit time constant by charging a 22 μf capacitor to 5 V and discharging through 100 kΩ, then measure voltage after one and 0.6 time constants.

Measure phase shift in an rl circuit by applying a 1 khz signal to an inductor and resistor, and observe input versus resistor voltage on a two-channel oscilloscope.

Build an rlc circuit on a breadboard, excite it with a function generator, and measure input and resistor voltages with an oscilloscope to analyze impedance and current.

Explore resonance in series and parallel rlc circuits by balancing inductive and capacitive reactances toward the resonant frequency. Use a function generator and oscilloscope to observe voltage responses.

We determine the resonant frequency around 10.7 kHz from the maximum output and identify half-power frequencies fL and fH. We compute bandwidth and quality factor, illustrating band-pass and band-stop behavior.

Explore passive low-pass filter design using an RC circuit, analyze frequency response, derive H(ω)=1/(1+jωRC), determine cutoff ωc=1/RC and f_c≈7.23 kHz, and validate with oscilloscope measurements.

Design and analyze a band-pass filter from a series RLC circuit. Resonance creates a passband between lower and upper half-power frequencies, centered around 33.9 kHz.
