Description
The code defines a circuit diagram using the TikZ package with the Circuitikz library. The circuit has a voltage source labeled "NI" connected to a resistor "R1", which is connected to another resistor "R2" and so on, forming a series circuit. Each resistor is labeled with its resistance value and a different color. The circuit also includes arrows indicating the direction of the current flowing through each resistor, labeled as phi_1, phi_2, and phi_3. Finally, there are labels for the voltage drop across each resistor, labeled as F_1, F_2, F_3, F_4, and F_g, where F_g is the voltage drop across the last resistor "Rg".
Keywords
