to the black test lead on the DMM.
5. it to the open lead of the resistor. Your circuit
look like the illustration above.
6. et the voltage control on the power supply to the zero output setting. Turn the power on and
lowly increase the output until you measure 10mA through the circuit. Have the instructor
heck your setting.
tor initial: ______________
. the voltage applied to the circ t when the power supply is adjusted so that there is a
current flow of 5mA?
Please review the voltage safety rules!
Ammeter
1. Disconnect the previous circuit. Set up the meter to read current in the range from 0 to 20mA.
With the power OFF, insert the 1k resistor into the breadboard section of the Elenco trainer.
Make sure the resistor leads are in separ
Connect a jumper from the positive variable power supply terminal to one side of the resistor.
4. Connect another jumper from the middle “ground” terminal
