MCQ of the day: Resistor, Capacitor and Inductor with 4, 12 and 15 V drop

Correct answer: a) 5V
Whenever capacitor, inductor and resistor are connected in series the original formula of KVL is not valid. Now for the voltage calculation a new formula is used:

V2 = V2 + (VC - VL) If VC>VL
&
V2 = V2 + (VL - VC) If VL>VC
