Varistors or voltage-dependent resistors play a critical role in electronic circuits, safeguarding them against transient voltage spikes. These spikes can originate from various sources, such as lightning strikes, inductive load switching, or electrostatic discharge. Understanding how to check a varistor is crucial for ensuring optimal circuit performance and preventing damage to sensitive electronic components. Checking…
A varistor is an electronic component used to protect circuits from voltage spikes. It is a type of resistor whose resistance decreases as the voltage across it increases. This means that when a high voltage is applied to the varistor, it will conduct electricity and divert the current away from the circuit. This can help…
Varistors are electronic components that protect electrical circuits from voltage spikes. They are typically used in power supplies, lighting circuits, and other applications where there is a risk of overvoltage. Varistors are available in a variety of sizes, shapes, and voltage ratings, so it is important to choose the right varistor for the application. When…
Selecting the appropriate varistor for a specific application requires careful consideration of various factors. Varistors, also known as voltage-dependent resistors (VDRs), are essential components for protecting electronic circuits from voltage surges and transients. Understanding the operating voltage, peak current, energy absorption capability, response time, and temperature range of the varistor is crucial. Additionally, considering the…
