Voltage-sensitive resistors, often called varistors, are special electronic components that change their resistance based on the voltage applied to them. They work like a sponge soaking up water, only instead of water, they soak up electricity. When the voltage goes up high, the varistor lowers its resistance. This means it lets more electricity flow through. When the voltage is low, the resistance goes back up, and less electricity flows. This behavior helps protect circuits and electronic devices from sudden spikes in voltage, which can cause damage. Zhongman offers a range of force sensing resistor that are reliable and used in many different projects, from small gadgets to big machines.
