State two application of fusible resistor?

1. Overcurrent protection: Fusible resistors are commonly used in electronic circuits as a form of overcurrent protection. When the current flowing through the resistor exceeds a certain threshold, the resistor will heat up and melt, breaking the circuit and preventing damage to other components.

2. Surge protection: Fusible resistors can also be used in surge protection circuits to absorb and dissipate excess energy from voltage spikes or surges. The resistor will heat up and absorb the excess energy, protecting sensitive components from damage.

1. Overcurrent Protection: Fusible resistors are used as a sacrificial element in overcurrent protection circuits, where they melt and break the circuit to prevent damage to downstream components during an overcurrent event.
2. Current Limiting: Fusible resistors are employed as current limiters in circuits to restrict current flow within a predetermined range, thereby protecting sensitive components from damage due to excessive current draw.
