Measurement using the oscilloscope:
Measure across the resistor the voltage value. To make the measurement with an
oscilloscope, you need:
Set the time base [SEC/DIV] and Volt time scale [VOLTS/DIV] of the oscilloscope in an
appropriate manner, so that the waveform of the measured voltage fills the screen of the
oscilloscope, as shown in fig.26 (the order of magnitude of exposure time to perform the
current measurement is of a few hundred ms)
fig. 26
If the measurement is performed correctly it is expected to see an average value of about
8 V (to each V corresponds 1 mA)
Measurement using the digital multimeter:
It is necessary to set the full scale of the multimeter in an appropriate manner in order to
measure the voltage across the resistance; then after positioning the end sleeves of the
multimeter across the resistor (as shown previously in fig.25) set an exposure time long
enough to allow the multimeter to read this voltage (the order of magnitude of the
exposure is approximately 1 sec). The value that is expected to read is like in the previous
case of about 8 V (to each V corresponds 1 mA)
