An audio amplifier provides an alternating rms emf of 15.0V a loudspeaker connected to the amplifier has a resistance of 10.4 w what is the rms current in the speaker?

Respuesta :

Answer:

Current in the speaker will be 1.442 A

Explanation:

We have given an audio amplifier of rms emf of 15 volt

So emf of the audio amplifier [tex]V=15volt[/tex]

Resistance of the amplifier [tex]R=10.4ohm[/tex]

We have to find the current

From ohm's ;aw we know that V = IR , here I is current and R is resistance

So [tex]15=I\times 10.4[/tex]

I = 1.442 A

So current in the speaker will be 1.442 A
