Main Uses:

This specific resistor with a low resistance value of 0.01 ohms and a high power rating of 5W could be used in various applications such as:

  • Power Supplies: Used as a current shunt resistor for measuring current flow.

  • Power Electronics: Used in circuits that require high power handling capacities.

  • Industrial Applications: Commonly used in industrial automation, power distribution, motor controls, etc.

Working Principle:

  • This resistor follows the basic principle of resisting the flow of electric current. At 0.01 ohms, it allows significant current to flow through while dissipating power.

  • A 1% tolerance means that the actual resistance of the resistor may vary by up to 1% from the stated value of 0.01 ohms.

  • The resistor's 5W power rating indicates the maximum power it can handle without getting damaged due to excessive heat generated during operation.

Given the specifications of this Vishay resistor (WSR5R0100FEA), it is more likely to be used in power electronics applications or where precise current measurements are necessary due to its low resistance value and high power handling capability.
