To find the current in amperes, we can use the formula:
Current (I) = Charge (Q)/Time (t).
Given:
Charge (Q) = 8/10 Coulomb = 0.8 Coulomb,
Time (t) = 4 seconds.
Plugging in the values, we get:
I = Q/t.
= 0.8 C/4 s,
= 0.2 A.
So, the current is 0.2 amperes.
Current (I) = Charge (Q)/Time (t).
Given:
Charge (Q) = 8/10 Coulomb = 0.8 Coulomb,
Time (t) = 4 seconds.
Plugging in the values, we get:
I = Q/t.
= 0.8 C/4 s,
= 0.2 A.
So, the current is 0.2 amperes.

First, we need to observe the question very carefully they mentioned that Eight-tenths (8/10).
So, I = Q/t.
= 8/10*4.
= 2/10.
= 0.2.
i=0.2 amperes.
So, I = Q/t.
= 8/10*4.
= 2/10.
= 0.2.
i=0.2 amperes.

Here the mention time (4s) only
But why you guys take
Q=8/10?
Is there any farmula? Please explain me.

Q=it Q= 8c or 10c t= 4 sec.
i=10/4=2.5A
i=8/4=2A.
2.5A is not given in the option, so the answer Will be 2A.
i=10/4=2.5A
i=8/4=2A.
2.5A is not given in the option, so the answer Will be 2A.

I have a doubt. How come 8/10?
Why not 8*10?
Please give the answer.
Why not 8*10?
Please give the answer.

I = q/t.
I = 8/10/4,
I = 8/10*4,
I = 8/40,
I = 0.2Amp.
I = 8/10/4,
I = 8/10*4,
I = 8/40,
I = 0.2Amp.

Q=8/10=0.8,
T= 4.
We know,
I= charge/time,
I= 0.8/4,
I=0.2amp.
And is option D.
T= 4.
We know,
I= charge/time,
I= 0.8/4,
I=0.2amp.
And is option D.

q =it.
=> i = q/t.
q = 8/10 = 0.8, t=4.
i = 0.8/4 = 0.2.A.
=> i = q/t.
q = 8/10 = 0.8, t=4.
i = 0.8/4 = 0.2.A.
