Answer:

30

Explanations:

Given the expression for the instantaneous voltage expressed as:

[tex]v=60\sin \theta[/tex]

Given the following parameter:

θ = 30⁰

Substitute the given parameter into the formula to have:

[tex]\begin{gathered} v=60\sin 30^0 \\ v=60(0.5) \\ v=30 \end{gathered}[/tex]

Therefore the instantaneous voltage when θ = 30⁰ is 30.
