In a certain stereo system, each speaker has a resistance of 4.90 . The system is rated at 68.0 W in each channel, and each speaker circuit includes a fuse rated 4.00 A. What is the maximum allowed current for each speaker?

The maximum allowed current for each speaker is 3.73 A

Explanation:

Given;

resistance of each speaker = 4.9Ω

power through each system channel = 68 W

the current through the fuse of the speaker circuit = 4 A

From ohms law, the maximum allowed current for each speaker is calculated as;'

P = I²R

Where;

p is power

I is current

R is resistance

I = √(P/R)

 = √(68/4.9)

 = 3.73 A

Therefore, the maximum allowed current for each speaker is 3.73 A

diagram is missing, but i will try to explain your doubt.

answer:

amplitude is the maximum displacement or distance moved on a point of a vibrating body or wave measured from its equilibrium position.it is equal to half the length of vibration path.
