An eight-pole wave-connected armature has 600 conductors and is driven at 625 rev/min. If the flux per pole is 20 mWb, determine the generated emf.

125 V
250 V
500 V
325 V

ANSWER EXPLANATION DOWNLOAD EXAMIANS APP

Let,
E→EMF in volt
φ→Flux in weber
A→Parallel path (for wave winding = 2)
Z→No. of armature conductors
N→speed in rpm
P = Number of poles
E = PφNZ/(60A)
E = 8*0.020*625/(60*2)
E = 500 V

Calculate the capacitance per meter of a 50 Ω load cable that has an inductance of 50 nH/m.

30 pF
10 pF
40 pF
20 pF

ANSWER EXPLANATION DOWNLOAD EXAMIANS APP

Z = √(L/C)
C = L/Z²
C = 50*10⁻⁹/(50*50)
C = 0.02 nF
C = 20 pF

A given solar cell has the following specifications:
Open-circuit voltage, Voc: 0.7 V
Short-circuit current, Isc: 3.5 A
Short-circuit current, Isc: 3.5 A
Short-circuit current, Isc: 3.5 A
If the solar cell operates at maximum power point, calculate the efficiency.

12.70%
15.70%
14.70%
13.70%

ANSWER EXPLANATION DOWNLOAD EXAMIANS APP

Equation is given by:
Efficiency = (F.F*Voc*Isc)/Pin
= (0.6*3.5*0.7)/10
= 0.14702
% efficiency = 14.7 %
