Kirchhoff's rules governing the current and electromotive forces in an electrical network are as follows:
1. Kirchhoff's Current Law (KCL): The algebraic sum of currents entering and leaving a node (or a junction) in an electrical circuit is zero. This law is based on the principle of conservation of charge, stating that the total current entering a junction must equal the total current leaving the junction.
2. Kirchhoff's Voltage Law (KVL): The sum of the electromotive forces (emfs) in any closed loop of an electrical circuit is equal to the sum of the voltage drops in that loop. This law is based on the principle of conservation of energy, stating that the total energy supplied in a closed loop must equal the total energy consumed in that loop.
These rules are fundamental in analyzing and solving electrical circuits, helping to determine currents, voltages, and power distribution within the network.
