2. For a shunt DC generator, define the concept of critical field resistance. Comment on the reason why the shunt field resistance of the generator must be smaller than the critical field resistance.
A second separately excited DC generator has the same electrical parameters as the generator in part (a) first but does not have compensating windings. The full-load demagnetising armature reaction is equivalent to 500 Ampere-turns. (i) With Radj = 63Ω and the generator is driven at 1600rpm, what is the no-load terminal voltage? (ii) What would be the output terminal voltage if 364A were drawn from the armature at 1600rpm? Q2. (a) Fig. Q20) shows a separately excited DC generator with...
A DC voltage generator outputting 10 volts is connected to two capacitors in parallel, who values of 4 and 5 Farads. What is the capacitance? What is the steady-state current?
the load current of a DC generator has been increased twice. does it affect it's output voltage
In C++ 1.Define a function named "sumCodes" that accepts two input parameters: "s "and "pos". "s" is an object of the type "string" and "pos" is a boolean value with the default argument of "true". If "pos" is "true", the function returns the summation of the ASCII codes of all the characters located at the even indices of "s" and if "pos" is "false", the function returns the summation of the ASCII codes of all the characters located at the...
Define a function named how_many_substr_of_string(...) which receives two parameters, the first parameters is a list with strings (name it listst) and the second parameter is a single string (name it st). The function should return a number, indicating how many of the strings in the list listst are substrings in the string st As an example, the following code fragment: listst = ["a","bc","dd"] st = "abc" res = how_many_substr_of_string(listst,st) print (res) should produce the output: 2 language:Python

Two dc generators (A) and (B) with the following characteristics: Generator (A): rated voltage = 150 V, rated current = 30 Amp, and armature resistance = 0.4 Ω. Generator (B): no-load voltage = 160 V, rated current = 20 Amp, and armature resistance = 0.6 Ω. are connected in parallel. Find: a) Circulating no-load current and terminal voltage. b) The load current when generator B floating. c) The maximum possible load power.
Define agency costs and discuss two ways in which these costs affect the value of a business How does the concept of agency costs apply to the issue of Assignment of Benefits (AOB)?
