➀
Use the voltage sensor in Analog Channel B to measure the peak voltage across each of the
components of the circuit individually. The sum of these peak voltages do not equal the applied
peak voltage. Why not? Draw a phasor diagram to explain this.
➁ Determine whether the resonant frequency depends on the resistance.
To see if the resistance makes a difference, set the Scope to the resonant frequency and then
replace the 10
Ω
resistor by a 100
Ω
resistor. Does the resonant frequency increase, decrease, or
stay the same?
