How do you change the resistance of a resistor? Sometimes you need a resistor with a value you don’t have in your kit. Instead of ordering and wanting for a resistor with a value you need you can change the resistance of a resistor by using another resistor or many. By installing resistors in a […]
What is the importance of instrumentation in industries?
What is the importance of instrumentation in industries? Instrumentation is the basic process control in industry. In industrial control a wide number of variables temperature, flow, level, pressure, and distance can be sensed simultaneously. All of these can be interdependent variables in a single processing require a complex microprocessor system for total control. What is […]
What type of light is emitted from a LED?
What type of light is emitted from a LED? LED is an abbreviation of Light Emission Diode, and is a device which emits light by flowing a current to the p-n junction like a semiconductor laser (LD). It emits various wavelength lights in the ultraviolet, visible and infrared regions, corresponding to its band gap energy. […]
How do you find the angle of twist?
What is hypothesis and examples?
Which of the following is a characteristic of urban sprawl?
Which of the following is a characteristic of urban sprawl? Urban Sprawl is generally characterized by discontinuous, haphazard, uncoordinated, unplanned or poorly planned urban development. It is characterized by low density, excessive consumption of land, automobile dependence, separation of land-uses, social segregation and displeasing aesthetics. What are the benefits of urban sprawl? Thanks to less […]
What are the 3 types of lighting?
What are the 3 types of lighting? 3 Basic Types of Lighting Ambient lighting. Task lighting. Accent lighting. What is the best type of lighting? LED bulbs fit standard light sockets and are the most energy-efficient option. LEDs have lower wattage than incandescent bulbs but emit the same light output. This allows them to produce […]
How does temperature affect conductivity of semiconductors?
How does temperature affect conductivity of semiconductors? As the temperature increases, more electrons get the energy to jump from Conduction band to valence band, and thereby increases the conductivity of the semiconductor. How does temperature affect electrical conductivity of metals? When temperature increases, the thermal speed of the electrons increases as well as, the amplitude […]
What is the difference between disturbed and undisturbed soil samples?
What is the difference between disturbed and undisturbed soil samples? Answer. Disturbed soil samples do not retain the in-situ properties of the soil during the collection process. Undisturbed soil samples retain the structural integrity of the soil and have a high recovery rate within the sampler. What is a disturbed soil sample? Disturbed soil samples […]
