A certain distribution transformer has nameplate data as follows:power rating 75KVAVoltage Rating 7200VAC/240VAC center tapped on the secondary for 240/120 VAC
impedance=4
It is desired to know the design impedence referred to the primary and to the secondary for basic engineering calculations and analysis
a. solve for the transformer impedance referred to the primaryb. solve for the tranformer impedance referred to the secondary
A rectangular loop of wire containing a high resistance voltmeter has corners initially at (a/2, b/2, 0), (-a/2, b/2, 0), (-a/2, -b/2, 0) and (a/2,-b/2, 0). The loop begins to rotate about the x axis at constant angular velocity w.
Determine the response of the system when aunit step is applied at input.
A TDM link has 20 signal channels and each channel is sampled 8000 times/sec. Each sample is represented by seven binary bits and contains an additional bit for synchronization. what is The total bit rate for the TDM link.
