Question

Given v = 60sinθ, what is the instantaneous voltage when θ = 610⁰?Question 1 options:56.38-20.52164.85-56.38

Answer 1

We are given the following

$v=60\sin \mleft(\theta\mright),\theta=610^{\circ\: }$

we can also replace

$\theta=610-360=250$

then

$\begin{gathered} v=60\sin \mleft(250^{\circ\: }\mright)=60\cdot(-0.93969) \\ v=-56.38155 \end{gathered}$

Therefore, the answer is the last one
