We, everyone, know calculation.
But the trick is we should find, is the circuit parallel or series.
It is pretty easy because the terminal from the VOLTAGE source is connected to the same terminals of both RADIO.

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.

Yes, according to current law it is ohms law.

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.

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.

That resistance are in series form.

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

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