It's the Earth leakage resistance (Ohm)
No, higher specific resistance means lower conductivity. Specific resistance is the resistance of a material per unit length and cross-sectional area, so a higher value indicates that the material resists the flow of electric current more effectively. Conversely, materials with lower specific resistance values are more conductive.
In the dark, an LDR (Light Dependent Resistor) will have a high resistance value as it is not exposed to light. When exposed to light, the resistance of an LDR decreases significantly due to the photoconductivity effect, making it more conductive.

To measure the resistance of a wire accurately, you can use a multimeter. Set the multimeter to the resistance measurement setting, then connect the probes to each end of the wire. The multimeter will display the resistance value in ohms. Make sure the wire is not connected to any power source and is not touching any other conductive material for an accurate measurement.

why semi conductive materials do not conduct current well & all of little value in their intrinsic state
Electrical conductivity is a material used in various electronic applications. Its ability to conduct electricity makes it an ideal material for transistors, transistors, switches, and other electronic components. Here’s how it can be tailored to meet the needs of a particular application. We’ll also discuss some of the key properties of conductive rubber that make it a career in e-commerce. Rubber below 10^4Ω is called conductive rubber. Conductive rubber not only has a high elasticity of rubber, but is also easy to process and form, and is light in weight. Rapid development leads to the increasingly wide application of polymer materials. When making conductive rubber products, raw rubber with a large dielectric constant is generally selected, such as silicone rubber, neoprene rubber, and nitrile rubber. Silicone rubber matrix is a better material for making conductive rubber products. It not only has the characteristics of electrical conductivity, high and low-temperature resistance, and aging resistance, but also has good process performance, and is suitable for manufacturing conductive rubber products with complex shapes and small structures; When used for electrical connection equipment, it can fit closely with the contact surface, is accurate and reliable, full of elasticity, and can play the role of shock absorption and sealing. Material selection should also be made according to the conditions of use of the product. For example, conductive rubber used in an environment in contact with oil is best to use oil-resistant rubber, such as nitrile rubber, chlorohydrin rubber, and neoprene rubber. Rubber combinations or rubber/plastic can also be used to make conductive rubber. EPDM, IIR, and PE can improve insulation (such as dielectric strength), PS/EPDM, PS/PBD, NBR/EPDM, NBR/IR, NR/CR, etc. are used together, with the help of an appropriate amount of hard colloid phase to make the conductive network structure. It is denser, or the conductive compounding agent such as carbon black is enriched in the phase interface region of the incompatible rubber pair, thereby improving the conductive performance. Therefore, the combination of rubber and rubber and plastic can use less filler to achieve the required conductive effect, which is beneficial to the flow of the rubber during processing and also reduces the hardness of the vulcanized rubber. The conductivity of conductive rubber depends largely on the type and amount of conductive fillers. The type and amount of fillers are crucial to the conductivity of rubber products. Commonly used conductive rubber fillers are granular carbon black, carbon fiber fillers, and metal conductive fillers such as gold, platinum, silver, copper, nickel, and other fine powders and flakes, foils, or processed into metal fibers, etc. These conductive fillers can provide electrical conductivity, improve the mechanical strength, fatigue resistance, and aging resistance of vulcanizates, etc. When the conductive filler particles reach a certain value, the conductivity will jump and increase sharply by several or ten orders of magnitude. After the conductive filler reaches or exceeds a certain critical value, the rubber filled with the conductive filler becomes conductive rubber. This critical value corresponds to the critical value at which the conductive filler particles in the composite material start to form conductive pathways. What is conductive rubber and what are its properties? Conductive rubber is a conductive polymer material widely used in applications involving the transmission and dissipation of electrical current. It mainly consists of elastic rubber and carbon black, which acts as a conductive agent in the rubber matrix. One of its most important properties is its flexibility, allowing it to adapt to any given shape or surface modification. In addition, due to the soft nature of rubber, it insulates well against shocks, prevents abrasion and vibration, and has superior weather resistance and durability compared to conventional materials. Additionally, its ability to form into any shape allows it to comfortably conform to the hand mounted on electrical equipment, eliminating the risk of electric shock from exposed metal edges. Overall, conductive rubber is an ideal solution for a variety of applications where conductivity and protection from physical damage are required.
