myDAQ Results:
Measure the capacitor voltage on AI0 and capacitor current on
AI1:
Arbitrary Waveform Generator Setup:
Use default X Range values (From=0 and To=1) for the other two segments.
Measure current at t 8ms:
Adjust = triggering and horizontal position to place the upper left corner of the voltage waveform at the 10ms grid
mark; use Cursor 1 for measurements and leave Cursor 2 at zero to make the cursor dT value match the given
voltage waveform timescale.
Measured value of the shunt resistor is 10.0 ohms.
Current at t = 8ms is 76.53 mV divided by 10.0 ohms 7.65 mA
Current at t = 25ms:
Current at t = 25ms is -52.35 mV divided by 10.0 ohms -5.24 mA
Current at t = 30ms:
Current at t = 30ms is -29.43 mV divided by 10.0 ohms -2.94 mA
