<h2>
Answer:</h2>
26.06°
<h2>
Explanation:</h2>
Given an RLC circuit [a circuit containing a capacitor, inductor and resistor], the phase angle (Φ), which is the difference in phase between the voltage and the current in the circuit, is given by;
Φ = tan⁻¹ [ ] --------------------------(i)
Where;
= inductive reactance of the circuit
= capacitive reactance of the circuit
R = resistance of the circuit
<em>From the question;</em>
= 16.5 Ω
= 9.41 Ω
R = 14.5 Ω
<em>Substitute these values into equation (i) as follows;</em>
Φ = tan⁻¹ [ ]
Φ = tan⁻¹ [ ]
Φ = tan⁻¹ [ 0.4890]
Φ = 26.06°
Therefore the phase angle of the AC series circuit is 26.06°
