KVL and KCL
KVL stands for Kirchhoff voltage law. KVL states that the total voltage drops around the loop in any closed electric circuit is equal to the sum of total voltage drop in the same closed loop.
Sign Convention
Science and technology incorporate some ideas and techniques of their own to understand a system skilfully and easily. These techniques are called conventions. For example: Sign conventions of mirrors are used to understand the phenomenon of reflection and refraction in an easier way.
First， Calculate the voltage across the 5.1kΩ resistor and the voltage across any one of the 1kΩ resistors
Second， Construct the series resistive network in figure (top). Check the interconnects between resistors for loose connections. Make sure they are properly connected. Use the DMM to measure the voltage across the 5.1kΩ resistor (figure middle) and any one of the 1kΩ resistors (figure bottom).
End，Compare the calculation and measurement. Comment on your finding
We need to find the voltage across 5.1 kohm resistor and the voltage across any one of the 1kΩ resistors.
