A voltage source Vs is used to apply two different voltages (12V and 18V) to the single-loop circuit shown in Fig. P1.18. The values of the measured current are shown in Fig. P1.18. The voltage and current satisfy the linear relation Vs=IR+V. where R is the resistance in ohms. I is the current in amps, and Vs is the voltage in volts.
(a) Using the data given in Fig. P1.18, and the equation of the line for Vs, as a function of 1, and determine the values of R and V. (b) Sketch the graph of Vs, as a function of I and dearly indicate the resistance R and voltage V on the graph.
