Rheostat A rheostat is a variable resistor which is used to control current. They are able to vary the resistance in a circuit without interruption.The construction is very similar to the construction of a potentiometer s. It uses only two connections, even when 3 terminals (as in a potentiometer) are present. rheostat is a variable resistor which is used to control current. They are able to vary the resistance in a circuit without interruption.

- The pot as we know it was originally known as a rheostat (or reostat in some texts) - essentially a variable wirewound resistor. The array of different types is now quite astonishing, and it can be very difficult for the beginner (in particular) to work out which type is suitable for a given task.

What Is a Rheumatologist? A rheumatologist is a physician who specializes in the diagnosis, management, and treatment of rheumatic and musculoskeletal diseases (e.g., arthritis, lupus).Rheumatic diseases are characterized by pain and inflammation in the joints and associated structures, and muscle soreness and stiffness. rheumatologist is a physician who specializes in the diagnosis, management, and treatment of rheumatic and musculoskeletal diseases (e.g., arthritis, lupus).

- What is a Rheostat? Rheostat is an adjustable or variable resistor. It is used to control the electrical resistance of a circuit without interrupting the flow of current. Rheostat has 3 terminals and usually consist of a resistive wire wrapped to form a toroid coil with a wiper that slides along the surface of the coil.

- Homeostasis or homoeostasis (homeo- + -stasis) is the property of a system in which variables are regulated so that internal conditions remain stable and relatively constant.Examples of homeostasis include the regulation of temperature and the balance between acidity and alkalinity (pH).It is a process that maintains the stability of the human body's internal environment in response to changes in external conditions.omeostasis or homoeostasis (homeo- + -stasis) is the property of a system in which variables are regulated so that internal conditions remain stable and relatively constant.

What Is Homeostasis? - Definition & Examples Definition of Homeostasis. Homeostasis is a key concept in understanding how our body works. It means keeping things constant and comes from two Greek words: 'homeo,' meaning 'similar,' and 'stasis,' meaning 'stable.' A more formal definition of homeostasis is a characteristic of a system that regulates its internal environment and tends to maintain a stable, relatively constant, condition of properties. Homeostasis is happening constantly in our bodies.

Rheumatology Rheumatology (Greek ρεύμα, rheuma, flowing current) is a sub-specialty in internal medicine, devoted to diagnosis and therapy of rheumatic diseases. Physicians who specialize in rheumatology are called rheumatologists. Rheumatologists deal mainly with clinical problems involving joints, soft tissues, autoimmune diseases, vasculitis, and heritable connective tissue disorders. Many of these diseases are now known to be disorders of the immune system. Rheumatology is increasingly the study of immunology. One of the major changes in modern rheumatology is the development of new drugs called biologics, or disease modifying agents, which can control severe disease more effectively.

Homeostasis and its Mechanism Homeostasis and its Mechanism. As mentioned earlier in the page homeostasis is the reletively stable conditions that the human body maintains to keep the internal environment of the body functioning healthily.This also allows cells for example the red blood cell function properly, to be able to carry oxygen around the body.s mentioned earlier in the page homeostasis is the reletively stable conditions that the human body maintains to keep the internal environment of the body functioning healthily.

- Registered health information technicians (RHITs) are custodians of one of the most important tools in modern health care—the medical record. These professionals ensure that patients’ histories are accurate, complete, up to date and properly entered into the clinical database.ost health information management work takes place behind the scenes in office environments. Technicians usually do not have direct patient contact but may speak with providers to double check facts and clarify ambiguities in records.

Rheostat  definition The resistance of the rheostat is depends on the length of the resistive track through which electric current is flowing. If we use the terminals A and B in the rheostat, the minimum resistance is achieved when we move the slider or wiper close to the terminal A, because the length of the resistive path decreases.

Difference Between Thermometer and Thermostat On the other hand, a thermostat is a controlling device which regulates the surrounding temperature of a system so that a desired value of temperature is maintained to keep the system safe. It works by switching heating or cooling devices on or off and maintains a steady level of temperature within them.

Difference Between Thermometer and Thermostat Thermostat is an instrument used to control the temperature of a system. A thermostat system consists of a temperature sensor, heat generator, and sometimes a cooling system. The operation of the thermostat is as follows. – take an input for the temperature stabilization. – measure the temperature of the system.

- Applications of rheostat. 1  Rheostat is generally used in the applications where high voltage or current is required. 2  Rheostats are used in dim lights to change the intensity of light. If we increase the resistance of the rheostat, the flow of electric current through the light bulb decreases.

Car Thermostat Replacement Service A thermostat is part of the cooling system that regulates the temperature of the coolant in the engine. The thermostat is a metal valve that has a temperature sensor built in. It can either be open or closed. When the thermostat is closed, it keeps the coolant in the engine. When the engine gets to a predetermined temperature, the thermostat opens allowing coolant to circulate. The circulation of coolant prevents the engine from overheating. If the thermostat fails to open, the car will overheat.

Relative humidity Please help improve it by rewriting it in an encyclopedic style. (September 2012) (Learn how and when to remove this template message) Relative humidity (RH) is the ratio of the partial pressure of water vapor to the equilibrium vapor pressure of water at a given temperature. Relative humidity depends on temperature and the pressure of the system of interest. It requires less water vapour to attain high relative humidity at low temperatures; more water vapour is required to attain high relative humidity in warm or hot air.
