WebA resistor is an electrical component that restricts the flow of electrical current in a circuit. The analogy often used to explain its operation is to consider current as water flowing in a hosepipe; a resistor can be considered as a constriction in the pipe that limits the flow of water. Most people will be familiar with Ohm’s law: V=IR. WebIf you get a reading that seems to be a common resistor value like 100 ohm or 1K, it is likely a resistor. If you get no reading at all across the component then it is either blown (possibly a fuse) or a capacitor. Here a multimeter with a capacitance funcion comes in really handy, measure the capacitance across it if you have access to a meter ...

WebAug 25, 2024 · Some fast-acting fusible resistors can react to sudden fault events, with fusing times < 20 µsec. A fusible resistor can replace both a fuse and resistor (or NTC thermistor to improve operating efficiency) on … WebA fusible resistor is a type designed to safeguard a circuit from damage. When the current load jumps faster than required, this resistor is built of a material that can fuse without flames or excessive heat generation. When you see this in a circuit, it appears rougher and larger and lacks the smoothness and luster of a standard resistor.
