Parallel Connection

Series Connection: A series connection is when components are connected one after another, creating a single path for the current to flow through.

Current Divider Rule: The current divider rule is used to calculate the amount of current that flows through each branch in a parallel circuit.

Equivalent Resistance: The equivalent resistance is the total resistance seen by the power source in a parallel circuit, calculated using Ohm's Law or by adding reciprocals of individual resistances.
