The phase angle between voltage and current in an RL series AC circuit can be calculated using the formula:
tan(θ) = XL / R
Given that R = 10 ohm and XL = 10 ohm, we can substitute these values into the formula:
tan(θ) = 10 / 10
tan(θ) = 1
To find the angle θ, we can take the inverse tangent (arctan) of both sides:
θ = arctan(1)
Using a calculator, we find that arctan(1) is equal to approximately 45 degrees.
Therefore, the phase angle between voltage and current in this RL series AC circuit is approximately 45 degrees.
