Total effective resistance = 8*8/8+8 = 4 ohm,
V=12 volt
So I = 12/4 = 3 Amp.
V=12 volt
So I = 12/4 = 3 Amp.

Actually current flow in the speakers is different due to parallel circuit. So. Do as above has explained.

Yes above calculation is correct.

Right calculation.

i1=v/r
i=12/8
i=1.5 Amp for speaker 1
similarly i2=1.5 Amp for another speaker 2
hence total current i=i1 + i2=3 Amp
i=12/8
i=1.5 Amp for speaker 1
similarly i2=1.5 Amp for another speaker 2
hence total current i=i1 + i2=3 Amp

The Answer of Harsha is also correct, bcos the total current will be addition of both & same current.

Thanks to rakesh and harsha.

It is simple calculation both speakers are connected parallel to source then total resultant resistance is 4ohms by ohms law I=V/R so, I=12/4=3amps.

I=V/R.
For first speaker I=12/8=1.5A.
For second speaker I=12/8=1.5A.
Hence total current=1.5+1.5=3A.
For first speaker I=12/8=1.5A.
For second speaker I=12/8=1.5A.
Hence total current=1.5+1.5=3A.
