Introduction

A resistor network, such as the 4820P-1-181, is a type of electrical component often used in circuits. It is designed to achieve a specific electrical purpose by providing resistance to current flow. This article describes the application field and working principle of these networks.

Application field

The application field of resistor networks is broad, but they are commonly used in applications such as audio circuits, amplifier circuits, bridge circuits and power supplies. They can be used to combine multiple resistors to perform a single function, such as providing a specific voltage in a circuit or limiting the current in a circuit. In audio circuits, resistor networks are often used to combine resistors in order to create a specific impedance. An example of this would be using a resistor network to achieve a 10K-ohm impedance in an audio amplifier circuit. In amplifier circuits, resistor networks are often used to provide a specific voltage or current level in the circuit. This is done by combining resistors connected in parallel or series to achieve a specific voltage or current level. For example, if multiple resistors are connected in series, the voltage applied across them will be the sum of the individual resistors\' voltage. In bridge circuits, resistor networks are used to transfer power from one lamp or other device to another. This is done by arranging resistors in a specific configuration to ensure the current flows in the desired direction. Resistor networks are also used in power supplies to provide a specific voltage and/or current level. This is done by combining resistors connected in parallel or series to achieve a specific output impedance.

Working Principle

The working principle of resistor networks is relatively simple. When multiple resistors are connected to each other in a specific configuration, the combined resistance of the network is determined by the individual resistances and the way they are connected. For example, if two resistors are connected in series, the combined resistance of the network will be equal to the sum of the individual resistors\' resistances. If two resistors are connected in parallel, the combined resistance of the network will be equal to the inverse of the sum of the individual resistances. The combined resistance of a resistor network can be calculated using Ohm’s law. This states that the resistance of a component is equal to the voltage applied across it divided by the current that flows through it. By applying Ohm’s law to a resistor network, the combined resistance, as well as the individual resistances, can be calculated. This is done by measuring the voltage and current of the network and then substituting these values into Ohm’s law.

Conclusion

In conclusion, resistor networks, such as the 4820P-1-181, are electrical components designed to achieve a specific purpose by providing resistance to current flow. They are used in a wide range of applications, such as audio circuits, amplifier circuits, bridge circuits and power supplies. Their working principle is based on Ohm’s law, which states that the resistance of a component is equal to the voltage applied across it divided by the current that flows through it. With this principle, the combined resistance of a resistor network as well as the individual resistances can be calculated.
