Questions:
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?
