Current =Coloumbs/Time. So, current = 40/20. Ans = 2A.

WKT., Current, I= dQ/dt Therefore, I = 40/20 = 2 Amperes.

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

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

Thanks for all

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.
