Question

This needs to be completed by making a VI in Labview. The voltage and power needs to be shown in a graph that has the the voltage plotting from 0 V to 100 V in increments of ten. 1. Assume that you have a resistive DC circuit with V=100 Volts and Power P=100 Watts. Write Virtual Instrument (Vi) module to display the following:

Resistance R and Current I

Answer 1

In LabVIEW, to display resistance and current for a given constant voltage and power, calculate resistance using R = V^2/P, and current using I = P/V. Create a VI that adjusts voltage from 0 to 100 V in increments of 10 and plot voltage versus current on a graph to visualize the linear relationship as per Ohm's law.

Step-by-step explanation:

To create a Virtual Instrument (VI) in LabVIEW that displays resistance (R) and current (I) for a resistive DC circuit given a constant voltage of 100 volts and power of 100 watts, we use the formulas for resistance and current derived from Ohm's law (V = IR) and the power equation (P = VI). The resistance can be calculated using the formula R = V2/P = 1002/100 = 100 Ω. The current can be obtained from P = VI which rearranges to I = P/V = 100/100 = 1 A.

In a LabVIEW VI, we would create controls to adjust the voltage from 0 V to 100 V in increments of 10, and read the corresponding current using an ammeter. A graph can be plotted with voltage on the x-axis and current on the y-axis to show the relationship between them. Since the circuit is resistive, this graph will be linear as per Ohm's law. To construct this in LabVIEW, you would use array functions, 'For' loops, and graphing tools available in the palette.
