Question

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?

Answer 1

Current in the speaker will be 1.442 A

Step-by-step explanation:

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

So emf of the audio amplifier
`V=15volt`

Resistance of the amplifier
`R=10.4ohm`

We have to find the current

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

So
`15=I* 10.4`

I = 1.442 A

So current in the speaker will be 1.442 A
