Distinguish between dependent and independent variables.

Question 2

Explain how you determined the magnitude of the divisions for both the x and y axes in order to plot a graph that utilizes the major portion of the graph paper.

Question 3

The graphs below show the phasors V_max and I_max for five RLC series circuits. The solid arrows represent the voltage phasors, V, and the dashed arrows represent the current phasors, I_max. Which graph represents a circuit where the capacitive reactance is greater than the inductive reactance?

a.

b.

c.

d.

Answer to Question 1

The independent variable produces a change in the dependent variable. The
dependent variable is, therefore, referred to as a function of the independent variable.

Answer to Question 2

The following is one method for choosing
convenient spacing. First, examine the data and determine the maximum values to be
plotted on each axis. Next, determine how many divisions are needed so that the
maximum value for each variable will fit on the graph. There are 10 divisions per
inch on each axis, so choose spacing that will make each division an even number.
This will make interpolation easier.
