1. The electric current I in amperes) passing through a resistor is related to the voltage V across a resistor (in volts) and the resistance R in ohms) by the formula If the resistor is connected across the terminals of a car battery (12 volts), construct a table of values of the current across the resistor for different resistor values from 2000 ohms to 5000 ohms. Use intervals of 1000 ohms. Plot these values as points in the Cartesian plane and connect the points. Is this a smooth curve or a straight line? ​
