Deformation leads to change in resistance.<\/p>\n<p>A variable resistance transducer is a device that converts a physical quantity, such as displacement, force, or pressure, into an electrical signal by changing its resistance. The resistance of a material is a measure of its opposition to the flow of electricity. When a material is deformed, its resistance changes. This change in resistance can be used to measure the amount of deformation.<\/p>\n<p>There are many different types of variable resistance transducers. Some common types include strain gauges, potentiometers, and rheostats. Strain gauges are the most common type of variable resistance transducer. They are made of a thin metal foil that is bonded to a substrate. When the substrate is deformed, the strain gauge changes its resistance. Potentiometers are variable resistors that are used to measure position or rotation. Rheostats are variable resistors that are used to control the amount of current in a circuit.<\/p>\n<p>Variable resistance transducers are used in a wide variety of applications. Some common applications include:<\/p>\n<ul>\n<li>Force measurement<\/li>\n<li>Pressure measurement<\/li>\n<li>Displacement measurement<\/li>\n<li>Rotational position measurement<\/li>\n<li>Temperature measurement<\/li>\n<li>Humidity measurement<\/li>\n<li>Flow measurement<\/li>\n<li>Level measurement<\/li>\n<\/ul>\n<p>Variable resistance transducers are a versatile and reliable way to measure a variety of physical quantities. They are used in a wide range of applications, from industrial control to medical diagnostics.<\/p>\n<p>Here is a brief explanation of each option:<\/p>\n<ul>\n<li>Option A: Deformation leads to change in resistance. This is the correct answer. When a material is deformed, its resistance changes. This change in resistance can be used to measure the amount of deformation.<\/li>\n<li>Option B: Displacement of a contact slider on a resistance. This is not the correct answer. The displacement of a contact slider on a resistance does not change the resistance of the material.<\/li>\n<li>Option C: Coupling of two coils changes with displacement. This is not the correct answer. The coupling of two coils does not change the resistance of the material.<\/li>\n<li>Option D: Movement of magnetic field produces variation in resistance of material. This is not the correct answer. The movement of a magnetic field does not change the resistance of the material.<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>[amp_mcq option1=&#8221;Deformation leads to change in resistance&#8221;
