Activity #2: Resistance from Current-Voltage Graph Directions: Calculate the resistance from the current-voltage graph below. Determine Resistance from Current-Voltage Graph Suppose you apply several different voltages across a circuit and measure the current that runs through the circuit. A plot of your results is shown in the figure below. What is the resistance of the circuit? grow . . ... . . .... .: ".. . Current (mA) . .. . . . ... . 1 2 3 45 .. .. Voltage (V) . .... . Note: current is given in milliamperes. Example, at 2 voltage, the current is 0.002A or 2 mA.Activity 2: Finding the PD now sill aleksi .V OF ai aining out DE Esmerb n Directions: Solve the following problems.
