A \( 12 \Omega \) resistor and a \( 0.21 \mathrm{H} \) inductor are connected in series to an a.c. source operating at \( 20 \mathrm{~V}, 50 \mathrm{cycle} / \) second. The phase angle between current and source voltage is (1) \( 30^{\circ} \) (2) \( 40^{\circ} \) (3) \( 80^{\circ} \) (4) \( 90^{\circ} \) 📲PW App Link - https://bit.ly/YTAI_PWAP 🌐PW Website - https://www.pw.live
