Explanation:

No answer description available for this question.

 Chandana said: (Dec 10, 2010) Root 3 times phase voltage.

 Anil said: (Apr 12, 2011) Phase voltage is 2000 volts. So line voltage mutiply with root3 valu = 1.732. 2000*1.732=3, 464volts.

 Bablu said: (May 23, 2011) Line voltage=root3 times of phase voltage.

 Lavanya said: (Jun 17, 2011) Line voltage = (root 3 times) of phase voltage.

 Saravana said: (Jul 12, 2011) Line voltage = root three times of phase voltage =1.732*2000 =3,464volts

 Siddu said: (Sep 13, 2011) In star connection line voltage equal to root 3 times of the phase voltage so answer is 2000*1.732=3464.

 Vibha said: (Nov 30, 2011) vl=root 3 of vph

 Shan said: (Dec 5, 2011) For Y(Star connection): Line Voltage=1.732* phase Voltage For Delta connection: Line Voltage= Phase Voltage. Accordingly, =2000*1.732 =3464.10 volts...

 Manohar Kr. Gaur said: (Dec 28, 2011) We know, vl=root3*vph then,vl=2000*1.732 =3464.10 volts

 Gajendra Singh said: (Feb 11, 2012) WKT V(line)=root3* V(Phase) i.e. V(line)=root3*2100 =3464.10volts

 Ajakpogha Ferdinand O. said: (May 14, 2012) Vl=root3*Vph = 1.7320*2000 = 3,464.1016V where Vl=Line Voltage Vph=Phase Voltage

 Puni said: (Aug 27, 2012) What about in delta conn?

 Chado said: (Dec 4, 2012) In wye connection: Line voltage = square root of 3 multiplied to Phase voltage while Line current = Phase current In delta connection: Line current = square root of 3 multiplied to Phase current while Line voltage = Phase voltage

 Venkidu said: (Jul 14, 2013) VL is equal to the Vph. VL = root3*Vph. = 1.732*2000. = 3464.1016V.

 Varadha Sit said: (Jul 14, 2013) VL= ROOT 3 INTO VP. VP = 2KV = 2000V. ROOT3 = 1.732. VL = 1.732  = 3464.

 Sanjay Verma said: (Nov 28, 2013) Line voltage = root three phase voltage, so 1.732*2000 = and is 3464.

 Saleem Pasha said: (May 14, 2014) Line voltage = root3 times phase voltage.

 Vishal said: (Aug 4, 2014) Why come 1.732 please answer I m not understand?

 Arunpandiyan M said: (Aug 19, 2014) VL = 1.732*VPH. VL = 1.732*2000. VL = 3464.

 Rajiv Gandhi said: (Nov 5, 2014) In a three phase system star connection line voltage is root of three so 2000kv multiply with root of three. It is right answer.

 Sandeep Wasnik said: (Jan 17, 2015) vl = root three*vph. = 1.73*2kv. = 1.73*2000. = 3460 volt.

 Karthi said: (Feb 19, 2016) In a three phase system star connection line voltage is root of three. So 2000kv multiply with root of three. In delta connection: Line current = Square root of 3 multiplied to Phase current while Line voltage = Phase voltage.

 B.Teja Sri said: (May 7, 2016) In Three phase system star connection vl = root(3)Vph. Given, 2kv = vph Where root(3) = 1.732. vl = 2000 * 1.732 =3464.

 Ranjan Gupta said: (Jul 17, 2016) 2kv = vph root three * vph. 1.73 * 2000. = 3460 VOLT.

 Karna said: (Aug 27, 2016) In star connection line current = phase current, Line voltage = 1/3 phase voltage. And in delta connection line voltage = phase voltage, Line current = root 3 phase voltage. So, how is the answer 'd' correct? By this star connection, the answer is 'c'. It's the right answer.

 Musahak Khan said: (Jan 28, 2017) Phase voltage = 2000v. So,line voltage = root3 * 2000 volt, = 3464volt.

 Musahak Khan said: (Jan 28, 2017) Phase voltage = 2000v. So,line voltage = root3 * 2000 volt, = 3464volt.

 Musahak Khan said: (Jan 28, 2017) Phase voltage = 2000v. So,line voltage = root3 * 2000 volt, = 3464volt.

 Siddu said: (Aug 29, 2017) Here, √ 3 * phase voltage.

 Hussain Nuhaadh said: (Nov 20, 2017) 1.7321 * 2000 = 3464.2.

 Sunil said: (Aug 29, 2018) VL =1.732 Voh. IL=Iph.

 Himanshu Dakre said: (Sep 3, 2018) In star connected systems, Line voltage is √3 phase voltage . i.e. = 2000 * √3 . Hence 3464 is the answer.
