As explained in the previous response, the correct answer is 2) 0.

Explanation

  • At resonance in a series RLC circuit, the inductive reactance (XL) and capacitive reactance (XC) are equal in magnitude but opposite in phase
  • This results in the voltages across the inductor (VL) and the capacitor (VC) being equal in magnitude and 180 degrees out of phase.
  • Therefore, the combined voltage across the inductor and capacitor is zero.
