Current is the rate of flow of charge.

So, i=q/t.

= 40/20.

= 2A.

GIVEN; C = 40C T = 20s.

Answer: Coulomb = 40c, Time = 20s.

I = Coulomb/Time.

= 40/20.

= 2A.

Current I = charge(q)/time(t).

I = q/t = 40/20 = 2A.

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

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

I=40/20=2A.

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

We know that I=Q/T.

Hence 40/20=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

CURRENT = CHARGE/ TIME.

I = Q/T.

I = 40C/20S.

I = 2A.

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

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

given that q=40c
t=20sec

i=40/20 A
i=2A.
