SUMMARY
The phase angle for the complex voltage and current relationship defined by the expression v(t) = (-1 + j√3)i(t) is determined using the formula tan⁻¹(√3 / -1). The discussion confirms that this approach is correct, leading to the conclusion that the phase angle can be calculated directly from the given components of the complex expression.
