The James Webb Space Telescope (JWSP) was finally launched into space on December 25, 2021, and is about to become one of the most important scientific instruments of our time. Name the major components of the JWSP shown in the figure below: (A) (B) (C) (D) (E) (F) (G) (H) (I) (J)

A 3Ø, 2000KW, 480V ∆-connected alternator is short-circuited and is operated at rated speed to produce rated current at 4A excitation. With the short-circuit remove and with the excitation adjusted to 5A, the voltage between stator terminal is 330V. The effective resistance between terminal as measured with dc is 2Ω. Determine the %V.R. of the alternator at half-load and pf of 0.8 leading without changing any given values.

A three-phase, wye-connected 2300 kVA and 6.6 kV generator operates at full-load.

The per-phase armature resistance Ra and the synchronous reactance, Xd, are

Simulation 1 Aim: Determine the true power dissipated in the load of a single-phase half-wave rectifier fed from a 220 V 50 Hz supply. The load resistor is equal to the last two numbers of your student number + 10 ohm. [25] 

The ram of a hydraulic press can exert a force of 12 KN if a force of 500 N is applied on the piston. If the diameter of the piston is 90 mm, calculate the diameter of the ram
