✅ Correct Answer: A
โ
Correct Answer: (A) Between the plates
๐ Explanation:
Step 1 โ Charging Process:
โข When a capacitor is charged, one plate gets <b>+Q</b>, the other gets <b>โQ</b>.
Step 2 โ Electric Field:
โข An <b>electric field E</b> is established in the medium between the plates.
Step 3 โ Energy Storage:
โข The work done in charging is stored as <b>potential energy of the electric field</b>.
U = ยฝ ร ฮตโ ร Eยฒ ร (Volume between plates)
โด Energy is stored in the <b>electric field between the plates</b>.
