1.Zero voltage regulation in a transformer occurs at :
(A)zero p.f. lead 
(B)unity p.f.
(C )leading p.f.
(D)lagging p.f.

2.A parallel plate capacitor has 15 p.F capacitance. If the linear dimensions of the plate are doubled and the distance between the plates are also doubled, then new value of capacitance would be :
(A)15uF
(B)30 uF
(C )60 uF
(D)7.5 u.F

3.Resistance of a 230 V 100 W bulb is R1 and that of a 230 V 75 W is R2. Then,
(A)R1= R2
(B)R1 > R2
(C )R1 < R2
(D)R1 - 2R2

ABSTRACT
Nanotechnology is one of the fastest growing fields in
research and technology. The main interest of
nanotechnology is not electrical power engineering but
there were a lot of possible applications to improve
electrical, mechanical, thermal or chemical properties of
electric power equipment. Often the economic aspect is
pointed out, but also a higher efficiency or a reduction of
losses predicts this new technology a successful appearance
in power engineering.
In this paper the state of the art in na ....etc

NANOTECHNOLOGY & MECHANICAL ENGINEERING


INTRODUCTION
We live in a world of machines. And the technical foundation for these machines lies in the steam engine developed during the 1780s by James Watt. The concept of deriving useful mechanical work from raw fuel such as wood, coal, oil, and now uranium was revolutionary. Watt also developed the slider-crank mechanism to convert reciprocating motion to rotary motion.
To improve on this first, basic engine, the people who followed Watt created the science of thermodynami ....etc

ABSTRACT



Because of high requirements in power, efficiency, installation space and weight, the design of electrical machines for hybrid electrical vehicles is a particular challenge. This seminar describes a comparative study allowing the selection of the most appropriate electric-propulsion system for a parallel hybrid electric vehicle (HEV). This seminar is based on an exhaustive review of the state of the art and on an effective comparison of the performances of the four main electric propulsion systems, namely the d ....etc
