LC Resonance circuits
The LC cicuit
- Design a parallel LC resonant circuit with a resonant frequency between 50-200 kHz. use [math]\displaystyle{ L }[/math] = 10 - 100 [math]\displaystyle{ \mu H }[/math], R = 1k [math]\displaystyle{ \Omega }[/math] .
- Construct the LC circuit using a non-polar capacitor
- Measure the Gain [math]\displaystyle{ \equiv \frac{V_{out}}{V_{in}} }[/math] as a function of frequency. (25 pnts)
- Compare the measured and theoretical values of the resonance frequency ([math]\displaystyle{ \omega_{L} }[/math]) (10 pnts)
Questions
- What is the bandwidth of the above circuit? (5 pnts)
The RLC cicuit
- Design and construct a series LRC circuit.
- Measure and Graph the Gain as a function of the oscillating input voltage frequency. (25 pnts)
- Measure and Graph the Phase Shift as a function of the oscillating input voltage frequency. (25 pnts)
Questions
- What is the current [math]\displaystyle{ I }[/math] at resonance? (5 pnts)
- What is the current as [math]\displaystyle{ \nu \rightarrow \infty }[/math]? (5 pnts)
