A light-emitting diode (LED) is a semiconductor device (p-n junction diode) that emits light when an electric current is passed through it. LEDs are becoming the most popular light sources because they are much more energy efficient than conventional incandescent light sources. While the "white" light produced by a light bulb or the sun is a blend of many different colors, and these sources typically produce a large amount of heat, LEDs release only one particular color of light, and...

A) When an alternating voltage of 200 V is applied across a device X, a current of 0.4A flows through the circuit and is in phase with the applied voltage. When the same voltage is applied across another device Y, the same current again flows through the circuit, but it lags behind the applied voltage by π/2radians. Name the devices X and Y.

1) A nozzle is a device for increasing the velocity of a steadily flowing stream of fluid. At the inlet to a certain nozzle the enthalpy of the fluid is 3025 kJ/kg and the velocity is 60 m/s. At the exit from the nozzle the enthalpy is 2790 kJ/kg. The nozzle is horizontal and there is negligible heat loss from it. (i) Find the velocity at the nozzle exit. (ii) If the inlet area is 0.1 m2 and specific volume...
