What are the advantages of closed loop system? Closed loop control systems are more accurate even in the presence of non-linearities. The sensitivity of the system may be made small to make the system more stable. The closed loop systems are less affected by noise. What is an example of a closed loop system? Two […]
Does a TV use chemical energy?
Does a TV use chemical energy? A television set is another device that operates by the transformation of energy. An electrical beam from the back of the television tube strikes a thin layer of chemicals on the television screen, causing them to glow. In this case, electrical energy is converted into light. How does a […]
What are 2 methods of searching an array?
What are 2 methods of searching an array? Searching Algorithms Sequential Search: In this, the list or array is traversed sequentially and every element is checked. For example: Linear Search. Interval Search: These algorithms are specifically designed for searching in sorted data-structures. What type of algorithm is performed in linear search? Linear search is a […]
How do you find the critical points of a function?
How do you find the critical points of a function? A critical point occurs when the derivative is 0 or undefined. If our equation is f(x)=mx+b, we get f'(x)=m. So if the function is constant (m=0) we get infinitely many critical points. How do you find the function of two variables? First, take the partial […]
Where is a strain gauge used?
Where is a strain gauge used? Strain gauges are used to measure the torque applied by a motor, turbine, or engine to fans, generators, wheels, or propellers. This equipment is found in power plants, ships, refineries, automobiles and industry at large. Power is obtained by measuring the strain and rotational speed on a shaft. How […]
What is the low voltage contact limit?
What is the low voltage contact limit? Section 680.2 defines the Low Voltage Contact Limit as. A voltage not exceeding the following values: (1) 15 volts (RMS) for sinusoidal ac. (2) 21.2 volts peak for nonsinusoidal ac. Is low voltage wiring required to be in conduit? Low-voltage wiring shall not be strapped to conduit. How […]
What is simple Vapour compression cycle?
What is simple Vapour compression cycle? Simple vapour compression cycle is a system where the suitable working substance is used, called as a refrigerant. It evaporates and condenses at pressure and temperature closes to atmospheric conditions. The refrigerant used is carbon dioxide, ammonia etc. Why is multi stage compression with intercooling adopted? Advantages of multi-stage […]
