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?

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

Resistance of the amplifier

We have to find the current

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

So

I = 1.442 A

So current in the speaker will be 1.442 A

because if the tool that you are using is not balanced it there would be false mass.

distance = 150m

displ = root (50 ^2 + 100^2)

root(2500+10000)

root 125000
