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.
