Why is a compact fluorescent light bulb more efficient than an incandescent bulb? The phosphor fluoresces to produce light. A fluorescent bulb produces less heat, so it is much more efficient. A fluorescent bulb can produce between 50 and 100 lumens per watt. This makes fluorescent bulbs four to six times more efficient than incandescent […]
How are folding doors used?
How are folding doors used? Folding doors can be used as internal or external room dividers and are made from a variety of materials. Most folding doors are glazed and the panels have frames of either wood, aluminium or upvc. They can open up and fold either internally or externally and are widely used in […]
What is the difference between single ended and differential signaling?
What is the difference between single ended and differential signaling? Single-ended inputs are lower in cost, and provide twice the number of inputs for the same size wiring connector, since they require only one analog HIGH (+) input per channel and one LLGND (-) shared by all inputs. Differential signals require signal HIGH and LOW […]
How does temperature affect the Nernst equation?
How does temperature affect the Nernst equation? Temperature does not affect Nernst equation. The variation of cell potential is linear with temperature. Nernst equation shows that cell potential decreases as temp increases if reaction quotient is not one and other terms stay constant. Does temperature affect Ecell? A. Temperature does not affect the e-cell when […]
Does capacitance increase with frequency?
Does capacitance increase with frequency? Capacitance does not change with frequency. Rather it’s the capacitive reactance that actually changes with frequency. Capacitance is simply the charge in a capacitor per voltage across its plates. What happens to capacitive reactance as the frequency of operation increases? The capacitive reactance of the capacitor decreases as the frequency […]
What is essentially the engine block of the rotary engine?
What is essentially the engine block of the rotary engine? The cooling system uses a standard radiator, thermostat, and radiator hoses. Water flows from the radiator to the water pump then into the rotor housing, which is essentially the engine block of the rotary engine; this is where the rotor moves. What is the bottom […]
What is a solution question?
What is a solution question? Below are four ways to recognize if your question is solution-oriented: It is a closed question. It asks for agreement with a proposition—would you, could you, shouldn’t you, how about if you. You can subtract a few words from the front and get a statement. The coach is proposing a […]

What are the methods for drawing isometric views?
What are the methods for drawing isometric views? Following method is used for drawing isometric scale: After drawing a horizontal line, draw two lines at 45° and 30° angle with it. Put marks on the 45° line according to the actual scale. Now draw perpendicular offsets from 45° line up to 30° line which will […]
What are the major hurdle of pipelining pipelining hazards?
What are the major hurdle of pipelining pipelining hazards? The Major Hurdle of Pipelining Control hazards—arise from changing the PC such as branch instructions For branch-taken situation, the instruction fetch is not in regular sequence, the target instruction is not available. Simple solution to the hazards → stall the pipeline. How do you overcome hazards […]
