Write down the readings you obtained above.Single battery: Volts/Div =Vertical deflection (cm) =Voltage (V) =Two batteries in series: Volts/Div = Penn State University Physics 212P-10 Written by Redwing and Samarth 1Vertical deflection (cm) =Voltage (V) =Exercise 2: Using the oscilloscope to measure the amplitude and frequency ofa periodic voltage signalQ2. Suppose you want to measure the frequency of an input signal using the scope. Describehow you would go about doing this i.e. write down an equation that relates frequency f, thesetting on the "sec/div" scale and the period of the sine wave as observed on the horizontal scale.Exercise 3: Using the oscilloscope to analyze a series R-L-C circuitQ3. Using an Excel spreadsheet, plot the voltage amplitude versus frequency. Include a printoutof the graph with your lab report.Q4. Approximately at what frequency is the voltage amplitude a maximum? (This is known asthe "resonant frequency" of the circuit.)Resonant frequency = _______________________Q5. We mentioned earlier that the impedance Z is a minimum at a particular "resonant"frequency. Use the expression for Z to show that the resonant frequency is related to the capacitorand the inductor in the circuit by:R= (LC)-1/2Use this relationship and the value of C = 100 F to deduce the value of the inductance L. Penn State University Physics 212P-10 Written by Redwing and Samarth
