Repeat Exercise 18 under the assumption that the relationship between the current I and the voltage drop V is best modeled by an equation of the form V = IR + c, where c is a constant offset value. This leads to a 5 × 2 linear system.
Exercise 18
Successive experiments are performed in which a known current (measured in amps) is passed through a resistor of unknown resistance R and the voltage drop (measured in volts) is measured. This results in the (p y) data (0.1, 1), (0.2, 2.1), (0.3, 2.9), (0.4, 4.2), (0.5, 5.1). The data is assumed to have measurement errors that prevent it from following Ohm's Law precisely.
