# Single-Source Circuit Implementation

## Design Challenge, Problem 3

This exercise uses concepts introduced in our experiment relative to implementing circuits with a single source. A link to this experiment is provided at the right.

Implement the circuit shown below on your breadboard. Measure the currents I1 and I2 as well as the voltage V.

Expected values for current and voltage are:

• I1 = 2.5mA
• I2 = 1.25 mA
• V = 1.25V

Compare your measured values with these expectations. Calculate a percent error between your measurements according to the formula:

${\rm{\% Error = }}\left. {\left| {\frac{{Measured - Expected}}{{Expected}}} \right.} \right| \times 100$

The vertical bars mean “absolute value”. The percent error will, therefore, always be positive. Comment on the agreement between your values and the expectations.
