# Source Voltages Greater Than 5V

## Design Challenge, Problem 1

This exercise uses concepts introduced in our experiment relative to implementing circuits with multiple sources that are greater than 5V. A link to this experiment is provided at the right.

Implement the circuit shown below on your breadboard. Measure the current I and the voltage V.

Expected values for current and voltage are:

• I = 3mA
• V = 3V

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.
