1. Examine your graph and state the relationship that exists between the current and voltage in the circuit, 2. For each set of data that you have recorded in the data chart, calculate the resistance by dividing the voltage (in volts) by the current (in amperes). Enter these calculations in the third column of the data chart. As the voltage is increased, does the calculated resistance increase, decrease, or rem in the same?
