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

given that q=40c
t=20sec

i=40/20 A
i=2A.

Ashok said: 1 decade ago

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

Thanks for all

Baalachandar said: 1 decade ago

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

Given current=charge in columbs/time in seconds so.

I=c/t =40/20=2a.

Anil said: 1 decade ago

i=c/t
c=40c
t=20s
i=c/t
i=40/20
i=2a

I=C/T
I=40/20
Hence I=2A

Quantity symbols units

coloumbs=current*time, Q=I*t , C=A*s,
coloumb/time=current , Q/t=I , C/s=A
40/20=2A

I=40/20=2 A

Sireesha said: 1 decade ago

current=charge/time
I=Q/t
I=40/20
I=2A
