No answer description available for this question.

 Kishorekumar said: (Oct 18, 2010) Current =Coloumbs/Time. So, current = 40/20. Ans = 2A.

 Namratha Nayak said: (Oct 18, 2010) WKT., Current, I= dQ/dt Therefore, I = 40/20 = 2 Amperes.

 Lakshmi said: (Oct 28, 2010) current =colums/time =40c/20s 2A

 Siva said: (Nov 22, 2010) current=charge/time I=40/20=2 Ampheres

 Sireesha said: (Dec 2, 2010) current=charge/time I=Q/t I=40/20 I=2A

 Vaishali said: (Feb 7, 2011) I=40/20=2 A

 Amandeep Singh said: (Mar 15, 2011) Quantity symbols units coloumbs=current*time, Q=I*t , C=A*s, coloumb/time=current , Q/t=I , C/s=A 40/20=2A

 Geetha said: (Apr 26, 2011) I=C/T I=40/20 Hence I=2A

 Anil said: (May 12, 2011) i=c/t c=40c t=20s i=c/t i=40/20 i=2a

 Kaavannan said: (May 12, 2011) Given current=charge in columbs/time in seconds so. I=c/t =40/20=2a.

 Baalachandar said: (May 24, 2011) Q=I*T Q=40C T=20S on subst. we get I=40/20 I=2A

 Anand said: (Jul 16, 2011) Thanks for all

 Ashok said: (Sep 18, 2011) I=COLOUMBS/TIME SO 40/20 =2 I=2A

 Chinna said: (Jan 13, 2012) Charge=current*time q=it i=q/t given that q=40c t=20sec i=40/20 A i=2A.

 Remya Raghavan said: (May 22, 2012) I=Q/T. Q=40c. T=20sec. I=40/20. I=2A.

 A Ravi Shankar said: (Jun 21, 2012) CURRENT = CHARGE/ TIME. I = Q/T. I = 40C/20S. I = 2A.

 Afzal said: (Jul 28, 2012) We know that Current= charge/time I=Q/T OR I=C/T C=40 T=20s I=40/20 I=2A

 Sailaja Sarath said: (Oct 8, 2012) We know that I=Q/T. Hence 40/20=2A.

 Laxman said: (Oct 15, 2012) Current= charge in Columb/Time in seconds. =C/T. =40/20. =2A.

 Shivakumar said: (Feb 21, 2013) Current = coloumb/time i.e I=C/t. Given: c=40c t=20s I=? I=40/20=2A.

 Monika said: (Jul 16, 2013) Current I = charge(q)/time(t). I = q/t = 40/20 = 2A.

 Nileshpatel said: (Oct 4, 2013) GIVEN; C = 40C T = 20s. Answer: Coulomb = 40c, Time = 20s. I = Coulomb/Time. = 40/20. = 2A.

 Prasanna said: (Nov 28, 2013) Current is the rate of flow of charge. So, i=q/t. = 40/20. = 2A.

 Azhagan said: (Jan 3, 2014) Current = charge/time. So, Current is 2A.

 Arun said: (Feb 23, 2014) Current = Charge flowing in 1 second. Charge flowing in 20 second = 40C. Charge flowing in 1 second = 40C/20s = 2A.

 Sharon said: (Mar 7, 2015) Current = Charge/Time. = 40c/20s = 2A.

 Rajendra said: (May 16, 2015) Current = coulombs/time. 1. Coulombs = 40 c. 2. Time = 20 s. Therefore current = 2 amps.

 Leninbabu said: (Aug 28, 2015) Current = Coulombs/Time. So here given values is 40 c & 20 s. Therefore 40c/20s = 2 A.

 Shanmu Sanjay said: (Jul 20, 2016) Current is the rate of flow of charge. So, Current = Charge/Time. Coulombs = 40 C. Time = 20 s. 40c/20s = 2 A.

 Chanu said: (Sep 16, 2016) Coloumbs/time = 40/20 = 2A.

 Siyum Abate said: (Mar 20, 2017) Current(I) = charge(Q)/time(T). = 40C/20s, = 2A.

 Dvijay said: (Feb 2, 2018) q=it so, q=40 , t=20 so that, I =q/t. I= 40/20=2A.

 Nishkarsh Jain said: (Aug 23, 2020) I = Q/T. I = 2A.
