A network connected between terminals $a$ and $b$ consists of two parallel combinations that are in series The first parallel combination is composed of a $16-\Omega$ resistor and a $48-\Omega$ resistor, The second parallel combination is composed of a $12-\Omega$ resistor and a $24-\Omega$ resistor. Draw the network and determine its equivalent resistance

Key Concepts

Circuit Diagrams

Circuit diagrams are graphical representations that show the interconnections between various elements of an electrical network using standardized symbols. They provide a visual framework that assists in understanding the structure of the circuit, ensuring clarity in the analysis and design of electrical systems.

Series Resistors

When resistors are connected in series, they are arranged end-to-end in a single path for the current. The equivalent resistance in a series circuit is the sum of the individual resistances, which is a key concept in simplifying circuit analysis and determining overall current flow.

Parallel Resistors

In a parallel configuration, resistors are connected across the same two nodes, which means the voltage across each resistor is identical. The overall or equivalent resistance is calculated using the reciprocal formula, where the reciprocal of the equivalent resistance equals the sum of the reciprocals of each individual resistance. This approach is essential in analyzing circuits where multiple current paths exist.

Equivalent Resistance

Equivalent resistance refers to the single resistance that can replace a network of resistors without altering the electrical behavior at the terminals. It simplifies the analysis of complex networks by reducing them to a single value computed through series and parallel combination rules.
