Q. An 8 - pole dc generator has 500 armature conductors and has a useful flux per pole of 0.065 web. What will be the emf generated if it is lap connected and runs at 1000 r.p.m. What must be the speed at which it is to be driven to produce the same emf if it is wave wound?
Ans.
E1 = N1PΦZ/60A = 10000 × 0.065 ×500 × P/A
For lap connection A = P
E1 = 10000 × 0.065 ×500 /60 = 541.67 volts
E2 = N28ΦZ/60 × 2
Since E2 = E1
8N2ΦZ/60 × 2 = 8N1ΦZ/60 × 8
N2 = N1 × 2/8 = 1000 × 2/8 = 250 rpm

Q. Why the gain of the amplifier decreases if the CE is avoided? When the ce is connected in the circuit, ac signals get bypassed through it to the ground. In the absence of Ce
