Consider a parallel plate capacitor of area A (of each plate) and separation 'd' between the plates.

Consider a parallel plate capacitor of area A (of each plate) and separation 'd' between the plates. If E is the electric field and ε₀ is the permittivity of free space between the plates, then potential energy stored in the capacitor is :- (1) 1/2(ε₀E²Ad) (2) 3/4(ε₀E²Ad) (3) 1/4(ε₀E²Ad) (4) ε₀E²Ad 📌 Understanding the Potential Energy Stored in a Parallel Plate Capacitor 🔋 The concept of energy storage in capacitors plays a fundamental role in electrostatics and electrical circuits. In this JEE Mains 2025 problem, we explore how the energy is stored in a *parallel plate capacitor* in terms of the electric field. This topic is crucial for understanding **capacitor-based circuits, energy storage, and applications in electronics**. Let's dive deep into the theory behind this problem and explore the detailed solution step by step. 🚀 --- 🧐 *Concept of Energy Stored in a Capacitor* A *parallel plate capacitor* consists of two conducting plates separated by a distance \( d \) with an insulating medium (vacuum or dielectric) between them. When a *potential difference (V)* is applied across the plates, an *electric field (E)* is established, and charge accumulates on the plates. This leads to the **storage of electrostatic potential energy (U)**. 🎯 *Key Takeaways* 🔹 The energy stored in a parallel plate capacitor depends on the electric field between the plates. 🔹 The *formula \( U = \frac{1}{2} \varepsilon_0 E^2 A d \)* helps in analyzing energy storage in capacitors without directly using capacitance. 🔹 This concept is useful in **electrostatics, capacitor circuits, and even electromagnetic wave theory**. 🔹 It forms the basis for understanding **dielectric capacitors, energy transfer in electrical circuits, and charge storage in electronic devices**. --- 📝 *JEE Mains 2025 Relevance* This question tests your understanding of **capacitor energy storage, electric field relations, and electrostatics**. It is a high-weightage topic in JEE Mains, often appearing in **electrostatics, capacitance, and modern physics applications**. #### 🎯 *Why This Concept is Important?* ✅ Used in *capacitor circuits* in DC and AC circuits. ✅ Basis for *energy storage* in electronic components. ✅ Helps in solving **problems involving work done by electric fields**. ✅ Essential for understanding **dielectrics and advanced electromagnetism**. --- 🔥 *Additional Conceptual Questions for Practice* 1️⃣ If the plate separation *d* is doubled, how does the energy stored in the capacitor change? 2️⃣ What happens to the energy stored if the dielectric medium is introduced between the plates? 3️⃣ How is the energy density related to the electric field in a capacitor? 4️⃣ If the charge on the capacitor is doubled, how does the stored energy change? By mastering this concept, you can solve many capacitor-related problems **quickly and efficiently in JEE Mains 2025**! 🚀 --- 🔗 *Stay Connected for More JEE Mains 2025 Solutions!* 📌 Follow for *detailed explanations, shortcuts, and problem-solving strategies* for JEE & NEET. 📌 Check out our *Instagram* for daily physics tricks and insights: [Physics Behind Everything](https://www.instagram.com/physics_beh...) 📌 Keep practicing, stay curious, and ace your exams! 🏆 --- 🔍 *Hashtags for Maximum Reach* #jeemains2025 #jeemains2025solution #jeemainsphysics #iitjee2025 #jeemains2025physics #jeemains2025electrostatics #capacitorenergy #physicswallah #iitphysics #jeephysicsprep #electrostatics #capacitorbasics #physicsfortoppers #jeepreparation2025 #iitjeephysics
