A reparality excited dc generator has OCC data at 1200 rmp as below.
At If = 6 A when loaded at Ia = 50 A, it has a terminal voltage of 230 V at speed of 1200 rpm. Given: Ra = 0.5 Ω.
(a) Determine the armature voltage drop due to the demagnetizing effect of armature reaction
(b) Assuming that this voltage drop in proportional to the square of armature current, determine the field current for a terminal voltage of 230 V at armature current of Ia = 40 A
(c) In part (a) determine the field current equivalent of demagnetization.
An 8-bit DAC outputs a value of 9.961 V when the input is FF (hexadecimal). What is the output when the input is 5A (hexadecimal)
In a CD player,the sampling rate is 44.1KHz and the samples are quantised using a 16bit/sample quantizer. Determine the resulting number of bits for a piece of music with a duration of 50 minutes
Apply a logarithm transformation to the data and repeat parts (a) and (b). Compare the tests from parts (b) and (c).What do these results indicate about the effect on a test of mild skewness when the sample sizes are fairly large?
