How does a bipolar junction transistor work?
How does a bipolar junction transistor work? Bipolar Transistors are current regulating devices that control the amount of current flowing through them from the Emitter to the Collector terminals in proportion to the amount of biasing voltage applied to their base terminal, thus acting like a current-controlled switch. What is the basic principle of a […]
How can a diode be used as a temperature sensor?
How can a diode be used as a temperature sensor? Set the temperature to 25°C, “soak” the part for a few minutes, and record the voltage across the diode. Repeat at –40°C and +85°C. With three points taken, the slope can be determined. An expression for the diode voltage over temperature is derived by using […]
What is traffic volume in transportation?
What is traffic volume in transportation? Volume Study Traffic volume is defined as the number of vehicles crossing a section of road per unit time at any selected period. Traffic volume studies are conducted to collect data on the number of vehicles and/or pedestrians that pass a point on a highway facility during a specified […]

How does a heat pump heating system work?
How does a heat pump heating system work? To provide heat, a heat pump works by extracting heat from the air outside of your home and transferring it to refrigeration coolant – the coolant is then compressed, which increases the temperature significantly; the coolant is then moved to the indoor unit of the heat pump, […]
What are the 3 parts of the 3D printing process?
What are the 3 parts of the 3D printing process? The 3 Basic Steps of 3D Printing Step #1) Modeling. Before a manufacturing company can build an object with a 3D printer, it must design the model using computer software. Step #2) Printing. The second step of 3D printing involves printing, or building, the object. […]
What happens when carbon content increases in steel?
What happens when carbon content increases in steel? Increasing carbon content increases hardness and strength and improves hardenability. But carbon also increases brittleness and reduces weldability because of its tendency to form martensite. Most steel contains less than 0.35 percent carbon. How does carbon increase the strength of steel? The use of carbon makes iron […]
Why is energy not always conserved?
Why is energy not always conserved? When we don’t ignore outside forces, such as those just mentioned, mechanical energy is not conserved. Energy is “lost” to friction in the sense that it is not converted between potential and kinetic energy but rather into heat energy, which we cannot put back into the object. Can energy […]
What enters the cylinder on the intake stroke of a diesel engine?
What enters the cylinder on the intake stroke of a diesel engine? When the piston is at the top of its cylinder it is on its compression stroke. The cylinder is filled with pressurized, super heated air. Diesel fuel is injected and ignites. How is the fuel delivered into the cylinder of a diesel engine? […]
