As for the working principle of the RN55E3321FBSL, it follows Faraday\'s law of electromagnetic induction, which states that an electric current produces a magnetic field and that a changing magnetic field generates electric current. The resistor is basically a conductor, albeit with a resistance value, and an electric current passing through the resistor will follow the direction of the conductor and its resistance. The magnetic field induced in the conductor by the current will concentrate around the resistor. The current is then limited by the increasing resistance and eventually the current reaches its limit, which is known as the Thermal Resistance.

The RN55E3321FBSL\'s operation conforms to the basic principles of Faraday’s Law of electromagnetic induction, and has the ability to control voltage and current in electrical circuits. When this type of resistor is used as a measure to control voltage, it can be used as a voltage regulator, while when used in limiting current, its application field is very wide.

In conclusion, the RN55E3321FBSL is a Through Hole Resistors device with a wide application field. Its working principle is based on Faraday\'s Law of electromagnetic induction, which enables the measure of voltage and current.
