Q=I*T
Q=40C
T=20S
on subst. we get
I=40/20
I=2A

Thanks for all

Ashok said: 1 decade ago

I=COLOUMBS/TIME
SO 40/20 =2
I=2A

Chinna said: 1 decade ago

Charge=current*time
q=it
i=q/t

given that q=40c
t=20sec

i=40/20 A
i=2A.

I=Q/T.
Q=40c.
T=20sec.
I=40/20.
I=2A.

CURRENT = CHARGE/ TIME.

I = Q/T.

I = 40C/20S.

I = 2A.

AFZAL said: 1 decade ago

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: 1 decade ago

We know that I=Q/T.

Hence 40/20=2A.

LAXMAN said: 1 decade ago

Current= charge in Columb/Time in seconds.
=C/T.
=40/20.
=2A.

Shivakumar said: 1 decade ago

Current = coloumb/time i.e I=C/t.

Given: c=40c t=20s I=?

I=40/20=2A.
