Question

3. A4 pole dc shunt generator with a shunt field resistance of 100 Q and an armature resistance of 10
has 400 lap connected conductors in its armature. The flux per pole is 20 mWb. The rotational loss is
500 Watts. If a load resistance of 10 Q is connected across the armature and the generator is driven
at 1200 rpm, compute
(a) the terminal voltage (Ans: 144.145 V)
(b) the efficiency (Ans: 68.42%)
(c) Voltage regulation (Ans: 11%)​

Answer 1

$Lim_{(x,y){\longrightarrow}{(0,0)}} \: \: \huge\frac{xy}{x^{2}y^{2}}$

$\pink{let ~(x,y)\longrightarrow (0,0)~ along~ the ~line ~y=x}$
