What is non ohmic Behaviour? A non- Ohmic device is one that does not have a constant resistance. A light bulb is a simple example; the filament undergoes huge changes in temperature when current passes through it. Therefore, the resistance of the filament is not constant, rather, it increases with increased current. What can cause […]

What is a combined heat and power system? CHP is an energy efficient technology that generates electricity and captures the heat that would otherwise be wasted to provide useful thermal energy—such as steam or hot water—that can be used for space heating, cooling, domestic hot water and industrial processes. What is an example of cogeneration? […]

What is the difference between traction and hydraulic elevators? A hydraulic elevator uses an electronic pump that pushes oil into a cylinder where the pressure is increased, pushing a piston and causing the elevator to rise. A traction elevator, on the other hand, uses a system of cables, pulleys, and counterweights to lift the cab. […]

How long does it take for alcohol to leave your system calculator? Blood: Alcohol is eliminated from the bloodstream at about 0.015 per hour. Alcohol can show up in a blood test for up to 12 hours. Urine: Alcohol can be detected in urine for up 3 to 5 days via the ethyl glucuronide (EtG) […]

How does methylmercury affect fish? Bioaccumulation of Mercury Fish absorb methylmercury from their food and from water as it passes over their gills. The older and larger the fish, the greater the potential for high mercury levels in their bodies. Fish are caught and eaten by humans and animals, causing methylmercury to accumulate in their […]

How many amps is 120 watts at 120 volts? 1 amp How many amps is 1320 watts? 11 Amps How do I work out the amperage of an appliance? Divide the watts of a given electrical item by the total number of volts available from the electric outlet to calculate amperage draw. The amount of […]

What are the controls in Visual Basic? Common Controls in VB.NET Control Text Box. As you can guess, it is used to accept textual input from the user. Button. It is used as a standard Windows Button. ListBox. As the name suggests, this control works as a way to display a list of items on […]

What does 1/8 of an inch look like? What does 1/8 of an inch look like on a ruler? The 1/8 of an inch marks are the smaller marks found directly in between the 1/4 of an inch marks on the ruler. Between 0 and 1 inch, there are marks that denote 1/8, 1/4 (or […]

What is considered an extraordinary item in accounting? An extraordinary item is an accounting term that refers to an abnormal gain or loss that is not generated from the ordinary business operations of a company, is infrequent in nature, and is unlikely to recur in the foreseeable future. Extraordinary items are disclosed separately in the […]

What is pure bending stress? Pure bending ( Theory of simple bending) is a condition of stress where a bending moment is applied to a beam without the simultaneous presence of axial, shear, or torsional forces. Pure bending occurs only under a constant bending moment (M) since the shear force (V), which is equal to. […]
