Solution:

Given that;

The voltage V of an audio speaker can be represented by


\begin{gathered} V=4√(P) \\ Where\text{ P is the power of the speaker} \end{gathered}

Where, P = 900, the voltage, V, will be


\begin{gathered} V=4√(P) \\ V=4√(900) \\ V=4(30)=120V \end{gathered}

Hence, the voltage is 120V
