Is air pressure higher above an airfoil? The shape of an airfoil causes air to flow faster on top than on bottom. The fast flowing air decreases the surrounding air pressure. Because the air pressure is greater below the airfoil than above, a resulting lift force is created. Why does the air flow faster over […]
How do you calculate ZL?
How do you calculate ZL? Line impedance is the ratio of complex line voltage to complex line current. You can calculate it with the following equation: Z(z) = V(z)/I(z). How do you find the input impedance of a transmission line? The input impedance of a terminated lossless transmission line is periodic in the length of […]

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 […]
