Below is a simple resistor network laid out on a breadboard:

All the resistors have resistance 1{\rm k}\Omega. The battery, which we will model as an ideal 9-Volt voltage source, is connected between the red and blue "rails".

Enter the voltages (relative to the blue rail) at the specified locations on the board, all in units of Volts. Locations are specified by row letter and column number. You may enter your answers as fractions or single numbers (accurate to within 1{\rm mV}).

Voltage (relative to blue rail) at location A9: 

Voltage (relative to blue rail) at location H9: 

Voltage (relative to blue rail) at location A12: 

Voltage (relative to blue rail) at location H12: 

Voltage (relative to blue rail) at location A15: 

Voltage (relative to blue rail) at location H15: 

Voltage (relative to blue rail) at location A18: 

Voltage (relative to blue rail) at location H18:
