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.

Current i = dq/dt.
Here the charge q = 8/10.
Time t = 4s.
Here as the charge is not changing with time.
Therefore the current equation becomes at instantaneous i = q/t.
i = (8/10)/4.
i = 8/40 = 2/10.
i = 0.2 A.

i = 8/40 = 2/10.
i = 0.2 A.

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.

Given, t = 4 sec, Q = 8/10 C.
We know that charge is directly proportional to current and time i.e. Q = it.
i = Q/t.
i = (8/10)/4.
i = 0.8/4.
i = 0.2 amp.

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.

Q = 8/10
t = 4 s
Now current i = Q / t that means current=charge/time
i = (8/10)/4
i = 2/10;
i = 0.2 A
t = 4 s
Now current i = Q / t that means current=charge/time
i = (8/10)/4
i = 2/10;
i = 0.2 A

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

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=8/10 c,
t=4 sec,
we know that,
I = Q/t(current = charge/time).
So I = (8/10)/4.
= 0.2A.
t=4 sec,
we know that,
I = Q/t(current = charge/time).
So I = (8/10)/4.
= 0.2A.

q = 8/10 = 0.8.
t = 4.
Current (i) = q/t.
i = 0.8/4 = 0.2.
That is a correct answer.
t = 4.
Current (i) = q/t.
i = 0.8/4 = 0.2.
That is a correct answer.
