Introduction

In the field of electrical engineering, a series network of resistors is a fundamental concept used to provide different voltages from a single source of energy. This concept is crucial in designing various electronic circuits, including voltage regulators, amplifiers, and power supplies. In this article, we will explore the concept of a series network of resistors and identify the correct term used to describe it.

What is a Series Network of Resistors?

A series network of resistors is a circuit configuration where multiple resistors are connected one after the other, either in a straight line or in a loop. Each resistor in the network has a specific resistance value, and the total resistance of the network is the sum of the individual resistances. When a voltage source is connected to the network, the voltage is divided across each resistor, resulting in a series of voltage drops.

How Does a Series Network of Resistors Work?

When a voltage source is connected to a series network of resistors, the voltage is divided across each resistor according to the ratio of their resistances. The voltage drop across each resistor is proportional to the resistance value and the total voltage applied to the network. The current flowing through the network is the same at all points, as there are no branches or parallel paths.

Types of Series Networks of Resistors

There are two main types of series networks of resistors: linear and non-linear. Linear series networks consist of resistors with constant resistance values, while non-linear series networks consist of resistors with varying resistance values.

Linear Series Networks

Linear series networks are the most common type of series network of resistors. They consist of resistors with constant resistance values, and the voltage drop across each resistor is proportional to the resistance value and the total voltage applied to the network.

Non-Linear Series Networks

Non-linear series networks consist of resistors with varying resistance values. The voltage drop across each resistor is not proportional to the resistance value and the total voltage applied to the network.

Voltage Divider

A voltage divider is a series network of resistors used to provide a specific voltage from a single source of energy. It consists of two or more resistors connected in series, with the output voltage taken across one of the resistors. The voltage divider is a fundamental concept in electrical engineering and is used in a wide range of applications, including voltage regulators, amplifiers, and power supplies.

Current Divider

A current divider is a series network of resistors used to provide a specific current from a single source of energy. It consists of two or more resistors connected in series, with the output current taken from one of the resistors. The current divider is not a common term used in electrical engineering, and it is not a standard concept in circuit analysis.

Power Divider

A power divider is a series network of resistors used to divide a power source into two or more branches. It consists of two or more resistors connected in series, with the output power taken from one of the branches. The power divider is not a standard concept in circuit analysis, and it is not commonly used in electrical engineering.

Energy Divider

An energy divider is not a standard term used in electrical engineering, and it is not a common concept in circuit analysis. The term "energy divider" is not related to the concept of a series network of resistors.

Conclusion

In conclusion, a series network of resistors used to provide different voltages from a single source of energy is called a voltage divider. The voltage divider is a fundamental concept in electrical engineering and is used in a wide range of applications, including voltage regulators, amplifiers, and power supplies. Understanding the basics of a series network of resistors and the concept of a voltage divider is crucial in designing and analyzing electronic circuits.
