Write an applet that provides a windowing interface to let a user enter two resistor values and choose which configuration to calculate. Include two text fields (label them Resistor 1 and Resistor 2) for the two input values, two buttons (label them Series and Parallel) to select the configuration, and another text field (label it Equivalent Resistance) to display the calculated value and indicate which configuration was selected. For example, if the user enters 100 for R1 and 50 for R2 and clicks the Series button, the message would read Series Equivalent = 150. If the user enters the same values and clicks the Parallel button, the message would read Parallel Equivalent = 33.3. Put the applet in a Web page that explains the calculations.
Every first-year electrical engineering student learns that two resistors (a resistor is a common type of electrical component) can be connected in either of two configurations— series or parallel—and that there are simple formulas to calculate the equivalent resistance of a single resistor that could replace the two. If R1 and R2 are the two resistor values, then Series resistance = R1 + R2, and Parallel resistance = (R1 * R2) / (R1 + R2). The applet can be created by copying code for any of the previously developed GUIs and may have any number of equally useful layouts. The solution shown here uses a five-row grid layout and two buttons, one to perform the calculations and another to clear all the text fields. The solution also tests for a variety of error conditions (e.g., no value entered for either or both resistors) and prints an appropriate message if the calculation cannot be performed.
