Final answer:
Three rules for solving parallel circuits are the Junction Rule, Loop Rule, and applying Ohm's Law to each branch individually.
Step-by-step explanation:
Kirchhoff's rules are used to solve parallel circuits. These rules are:
- Junction Rule: The sum of all currents entering a junction must equal the sum of all currents leaving the junction. In other words, the total current entering a junction splits into different branches, and the sum of the currents in those branches must equal the total entering current.
- Loop Rule: The algebraic sum of changes in potential around any closed circuit path (loop) must be zero. This means that as you move around a closed loop in the circuit, the sum of the potential differences across all the elements (resistors, batteries, etc.) in the loop must add up to zero.
- Ohm's Law: In parallel circuits, Ohm's Law can be used individually for each branch. This law states that the current flowing through a conductor is directly proportional to the voltage and inversely proportional to the resistance.
