Activity: Operating the Equipment

￿Measuring Data

uCheck the values of the AC power supply, resistor, coil, and capacitor, and then switch on the power supply.

uPrepare the Voltage Measurement Setup and measure voltage.

uDisplay and compare the change of voltage across each component.

Make sure that the individual voltage value across the resistor, capacitor, and coil does not exceed 5V. Consequently, you should make sure that the power supply voltage for the combination shown here does not exceed 3V.

Using a Calculator Program

Find the applicable program in the Program Library (P.2-16-3), input it into your calculator, and then run it.

uDisplay VR, VC, and VL.

VR(V) : Voltage Across the Resistor (CH1)

VC (V) : Voltage Across the Capacitor (CH2)

VL(V) : Voltage Across the Coil (CH3)

t(s) : Time

u Consider what type of combination would be required to keep voltage across all parts below 5V.

uConsider combinations that satisfy conditions for resonance.

uConsider what component combinations would satisfy the conditions of this activity (5V or less across each component, resonance circuit) for other AC frequencies.

uPerform FFT analysis and compare the frequency of each component.
