(a) How much power is dissipated in a short circuit of 240-V AC through a resistance of 0.250 Ohms? (b) What current flows? A 700 Ohms resistor is connected to a 9 V battery. The current is 0.1286 J. Calculate the power dissipated in the resistor. ...
Why do current flows in the opposite direction of electrons movement? State the term convection. Why does turbulent flow separate more than laminar flow? How is AC electrical power generated? Explain how a hot air balloon flies? What would atmospheric circulation would we predict if the earth wa...
saw blades, lathe bits, drill bits, router bits and dental drilling tips are generally made of carbide. Carbide is so popular in these sorts of tools because it stays sharper longer than most other materials. Additionally, someball-point pensuse carbide...
(2006) compare cash flows from derivative transactions with benchmark cash flows to investigate whether firms gain or lose money from selective hedging. Moreover, the literature also documents the relevance of these prior outcomes on risk attitudes and decision-making. While Thaler and Johnson (1990...
Current always flows in the same direction between those two terminals. The power that comes from a power plant, on the other hand, is called alternating current (AC). The direction of the current reverses, or alternates, 60 times per second (in the U.S.) or 50 times per second (in ...
As mentioned above, the current is the intensity or rate of flow of an electric charge. In DC systems, the current flows in one direction, “unidirectionally.” Familiar sources of DC current include batteries and solar cells. AC vs DC current ...
1. The role of inductors in alternating current When the alternating current flows into the inductor and the inductor will hinder its change. It doesn't make it big at once but increases slowly. When the AC power is off, the alternating current inductor will not lose at once, but slowly ...
Here we show how major rivers can efficiently connect to the deep-sea, by analysing the longest runout sediment flows (of any type) yet measured in action on Earth. These seafloor turbidity currents originated from the Congo River-mouth, with one flow tr
The work-around is to add column AC, and to use the condition $E$1:$AC$1<C2 . --- ERRATA... In a previous posting, the formula of the form NPV(B$2, C3:I3) is incorrect because Excel NPV discounts the first cash flow. Effectively, that discounts cash flows to the...
The high-pressure liquid refrigerant flows from the receiver-dryer through the expansion valve, where it is allowed to expand. This expansion reduces the pressure on the refrigerant, so it can move into the evaporator. The valve senses pressure and regulates the flow of refrigerant, which allows...
