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

4.The current in a series ....etc

Interception Probability and
Shielding Against Lightning
A comprehensive analysis on shielding against lightning is presented in this article. The design of its protection zone and collection volume is an important topic for an air terminal. The lightning interception
probability is a term which refers to the close conformity between the actual and calculated number of lightning strikes. The data shows that there is a relationship between the calculated and actual number lightning strikes. for an accurate description of lightning i ....etc

Abstract
The application of a superconductor to a faultcurrent limiter in a power system has been researched.We developed a magnetic shielding type superconductingfault current limiter using a Bi2212 thick film cylinder.This limiter consists of a primary winding on asuperconducting cylinder for generating an AC magneticfield, the cylinder for shielding the field, an iron core formagnetic members and a control ring for controlling faultcurrents. When a fault occurs, the superconductivecylinder quenches and a magnetic circuit is formed ....etc

New Technology for Preventing Residential Electrical Fires: Arc-Fault Circuit Interrupters (AFCIs)




INTRODUCTION

Annually, over 40,000 fires are attributed to home electrical distribution systems.
These fires result in more than 300 deaths and over 1,400 injuries each year. Statistics
from 1992-1996 show level trends in each of these estimates with no indications of
decline. In 1996, $680 million in property loss was attributed to home electrical
distr ....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
