Equivalent Resistance

Definition

Equivalent resistance refers to the total resistance in a circuit when multiple resistors are connected in series or parallel. It is the single resistor that would produce the same amount of current flow as all the individual resistors combined.

Analogy

Imagine you have a group project where each member represents a resistor. The equivalent resistance is like having one person who can do the work of all the members combined, making it easier and faster to complete the project.

Series Circuit: A series circuit is a circuit configuration where components are connected end-to-end, creating a single path for current flow.

Parallel Circuit: A parallel circuit is a circuit configuration where components are connected side by side, providing multiple paths for current flow.

Ohm's Law: Ohm's Law states that the current flowing through a conductor between two points is directly proportional to the voltage across those points and inversely proportional to the resistance.
