What is current divider rule and voltage divider rule?

The current divider rule is a technique used in electrical circuits to determine the current flowing through parallel branches. It states that the current through a branch is proportional to its resistance and inversely proportional to the total resistance of the parallel circuit. Conversely, the voltage divider rule is used to find the voltage across a component in a series circuit, where the voltage drop across a resistor is proportional to its resistance relative to the total resistance. Both rules facilitate the analysis of circuits by simplifying calculations for current and voltage distribution.
