What is the phase angle for a series rlc circuit containing
a50-w resistor,
a10-mf capacitor, and
a0.45-h inductor, when connected to a 60-hz power supply?

To solve this problem we will apply the concepts related to angular frequency, which can be calculated with the given frequency. In turn, with this frequency you can calculate the capacitive reactance and inductive reactance. The angle phase depends on the tangent of these two variables. So  if we have that,

The angular frequency,

The capacitive reactance

Inductive reactance

Phase angle is equal to

Since the phase angle is negative, the circuit is purely capacitive and the current leads the voltage by angle 59.4°

i think it’s a. this is because if they measured the mass of something with a mass of 150g, then their final answer would have to be approximately 150g. though all of their answers are almost 150, rosa and tran have the closest answers (or the exact answer) to the accurate one.
