Ya its correct according to ohms law,
V = IR.
To find I,
Let I = V/R.
12/4 = 3A.
V = IR.
To find I,
Let I = V/R.
12/4 = 3A.

The speakers are in the parallel form the main current gets divided 8||8 = 4 ohms and 12/4 = 3A.

R = 4 I.
I = V/R.
I =12/4 = 3 A.
I = V/R.
I =12/4 = 3 A.

That resistance are in series form.

At first let you know these speakers are connected in parallel manner. Positive of amplifier to both of speakers and negative of amplifier to both of speakers. So put parallel resistance formula to get equivalent resistance.

The above answers are correct.

Total effective resistance first find of both speakers.
8 * 8/8 + 8 = 64/16 = 4.
V = 12,
V = IR,
I = V/R = 12/4 = 3A.
8 * 8/8 + 8 = 64/16 = 4.
V = 12,
V = IR,
I = V/R = 12/4 = 3A.

Yes, according to current law it is ohms law.

The two speakers are connected in parallel.
So, Rp= 4Ω.
According to Ohm's law:
I = v/r,
12/4=3 A.
So, Rp= 4Ω.
According to Ohm's law:
I = v/r,
12/4=3 A.
