If two resistors with resistances \( R_1 \) and \( R_2 \) are connected in parallel, as shown in the figure, then the total resistance \( R \), measured in ohms (\( \Omega \)), is given by \[\frac{1}{R} = \frac{1}{R_1} + \frac{1}{R_2}.\]**Diagram Explanation:**The image shows a diagram of a parallel circuit with two resistors labeled \( R_1 \) and \( R_2 \). These resistors are connected across a parallel configuration with a voltage source.**Problem Statement:**If \( R_1 \) and \( R_2 \) are increasing at rates of 0.3 \(\Omega/s\) and 0.2 \(\Omega/s\), respectively, how fast (in \(\Omega/s\)) is \( R \) changing when \( R_1 = 50 \, \Omega \) and \( R_2 = 80 \, \Omega \)? (Round your answer to three decimal places.)\(\boxed{} \, \Omega/s\)

For each of the three simple circuit boards you will need to calculate the total resistance Reg for the entire circuit board by using the measured resistances of each of the resistors, and the equations given to you in the theory section. Then using the applied voltage of 2V, as the theoretical voltage Vth for the entire circuit board you can calculate the theoretical current, ith, for the entire circuit board.
