Resistors and Ohms Law - Voltage-Current Characteristics

(Figure 1)

Schematics of circuit (Figure 1).

Actual set-up of circuit (Figure 2).

This simple circuit consisted of a voltage source (Analog 

Discovery) connected to a 100 Ω resistor.

     

 
   

                                         

(Figure 3)

Figure 3 to the right shows the measured resistance of the resistor, which we found to be 97.9 Ω. This value will be later used to be compared to the slope of the current versus voltage graph.

(Figure 4)

Figure 4 is a table of the gathered data. Our group varied the voltage source between 0 V and 1.8 V in increments of 0.2 V. We measured the current running through the resistor at each voltage value with a digital multimeter. We will take these numbers and construct a graph show the
relationship between voltage
and current. The voltage will
go on the x-axis and the current
will go on the y-axis.
