TECHNICAL PAPER-40 QUESTION, 45- MINUTES
(1)in a ckt. We r giving voltage of 50 Hz as well as 60. then what will be the resultant frequency.
(a)less than 50 (b) more than 60 (c) in between 50 & 60
(d) none……….according to our conclusion answer will be none because if we apply two frequency component resultant frequency we can not say with such an ease’s should confirm the answer
2.In a ckt a single resistor is connected across a d.c. source, what will be the effect on current in first resistor if we connect one more resistance in parallel with earlier one….
Answer.. no change since it is a parallel combination.
