How do you calculate VC in a RC circuit? RC Charging Circuit Example No1 At 0.7 time constants ( 0.7T ) Vc = 0.5Vs. Therefore, Vc = 0.5 x 5V = 2.5V. At 1 time constant ( 1T ) Vc = 0.63Vs. Therefore, Vc = 0.63 x 5V = 3.15V. 1 time constant ( 1T […]
How do you calculate the frequency of an oscillator ring?
What is compressible and incompressible flow?
What is compressible and incompressible flow? Incompressible flow means flow with variation of density due to pressure changes is negligible or infinitesimal. All the liquids at constant temperature are incompressible. Compressible flow means a flow that undergoes a notable variation in density with trending pressure. What is the difference between compressible and incompressible fluids? The […]
What is fairness in economics?
What is fairness in economics? A large part of fairness research in economics has focused on prices and wages. With respect to prices, for example, consumers are generally less accepting of price increases as result of a short term growth in demand than rise in costs (Kahneman et al., 1986). What do behavioral economists believe? […]
What happens to diffraction pattern when distance between slits within the grating is increased?
What happens to diffraction pattern when distance between slits within the grating is increased? If we move the screen farther from the double slit, the screen will intercept the light from the grating after the bright lines in the pattern have been able to spread out farther, increasing the distance between the bright spots on […]
What is the process of dehumidification?
What is the process of dehumidification? The dehumidification process is the inverse of adding water to the room with an evaporative cooler, and instead releases heat. Therefore, an in-room dehumidifier will always warm the room and reduce the relative humidity indirectly, as well as reducing the humidity more directly, by condensing and removing water. What […]
How can we prevent occupational injury and ill health in the workplace?

Educate employees and management staff. Research safety vulnerabilities. Provide protection equipment. Have adequate staffing levels. Don’t take shortcuts. Inspect and maintain all company vehicles. How does a well […]
What uses a low open circuit voltage to start the arc?
What uses a low open circuit voltage to start the arc? Torch: A device used in the TIG (GTAW) process to control the position of the electrode, to transfer current to the arc and to direct the flow of the shielding gas. Touch Start: A low-voltage, low-amperage arc starting procedure for TIG (GTAW). How does […]
