Equivalent resistance for 2 resistors in parallel:

$\overline{){{\mathbf{R}}}_{{\mathbf{eq}}}{\mathbf{=}}\frac{{\mathbf{R}}_{\mathbf{1}}{\mathbf{R}}_{\mathbf{2}}}{{\mathbf{R}}_{\mathbf{1}}\mathbf{+}{\mathbf{R}}_{\mathbf{2}}}}$

A. Using the schematic of the circuit, calculate the total resistance of the circuit

B. Based on the theoretical value of R_{3} and the voltage measured at R_{3}, calculate the theoretical value of the current I_{3} using Ohm’s Law

C. What do the results suggest about the current coming into a junction and the current leaving a junction
