Using the Multimeter as an Ammeter

An ammeter is a device for measuring current. It measures the current flowing from the red to the black probes within the meter. The ammeter is placed in series with the circuit element whose current is to be measured. Recall that two elements are in series when they share in the same branch and hence share the same current. Consider the current divider circuit shown in Figure gif.

The current through may be expressed as a fraction of in terms of and using current division

 

You will now build the current divider circuit and make several measurements. Record all measured values and present percent error calculations and tables as appropriate.
