Materials needed:2 resistors – 680
12V Battery or 12V power supply
Copper wireExperimental Breadboard
This is a neatly drawn schematic of a series circuit.
Circuit correlation
It may not look so neat when wired to work.It is your job to make the correlation between the circuit schematic and the actual circuit.
Component placementPlace resistors on copper strips – each end on a different strip.
Power supply connection
Red lead is from power supply positive terminal jack– connects directly to left side of resistor R1.Black lead is from power supply negative terminal jack – connects directly to bottom of resistor R2.
Jumper placement
Use a copper wire to make jump from resistor R1 to resistor R2.
Completed circuit
Now you have a complete circuit.
Final correlationNow you have a complete circuit.

Now that the components are properly placed on the breadboard, it is time to set up the power source.

ports
We will not be using the Slave side at this time.
Nor will we be using the fixed 5V output ports
This is the master output – black is negative and red is positive – these leads go to
power your circuit.
Left and right TRACKING buttons are
out for independent adjustment of master /
slave outputs.
This is the master VOLTAGE adjustment knob.
Notice we have adjusted the master VOLT meter for 12.0V
This is the master CURRENT adjustment.
Notice we have adjusted the knob about midrange
This is the master CURRENT adjustment overload indicator.The most important thing is to adjust the master CURRENT knob just high enough to keep
this indicator off
This button powers the supply ON / OFF.Settings are retained while power supply is
off.
Keep power supply OFF while not actively taking measurements.
Keep power supply OFF while makingcircuit modifications.
