Video Credti: Jonathan M. Sullivan-Wood

When using the Ohm meter the 100K resistors work best.  With the series resistors you should have a reading of approx. 200 kilo-ohms, and with the parallel set the reading should be approx. 50 kilo-ohms.

NOTE:  Do not use the Ohm Meter on a live circuit, as this will damage the meter.

We can also monitor Voltage and Current on these types of circuits.  In this case the 10 K resistors seem to work the best.  The voltage drops across the resistors can be measured as well as the current in each circuit.
