The correct Answer is:
To solve the question, we need to analyze the two statements provided: **Statement 1:** Energy stored in the capacitor is less than the energy provided by the battery during the charging of the capacitor. **Statement 2:** Some of the energy is converted into heat. ### Step-by-Step Solution: 1. **Understanding the Energy Stored in a Capacitor:** The energy (U) stored in a capacitor with capacitance \( C \) and voltage \( V \) is given by the formula: \[ U = \frac{1}{2} C V^2 \] 2. **Understanding the Energy Provided by the Battery:** When a battery provides charge \( Q \) to the capacitor, the work done (W) by the battery is given by: \[ W = Q \cdot V \] Since the charge \( Q \) on the capacitor is related to capacitance and voltage by \( Q = C V \), we can substitute this into the work done: \[ W = C V \cdot V = C V^2 \] 3. **Comparing the Two Energies:** Now we compare the energy stored in the capacitor and the energy provided by the battery: - Energy stored in the capacitor: \( U = \frac{1}{2} C V^2 \) - Energy provided by the battery: \( W = C V^2 \) From this, we can see that: \[ W - U = C V^2 - \frac{1}{2} C V^2 = \frac{1}{2} C V^2 \] This shows that the energy provided by the battery is greater than the energy stored in the capacitor. 4. **Understanding Energy Loss:** The difference in energy \( \frac{1}{2} C V^2 \) represents the energy that is lost in the circuit, primarily due to resistive heating (Joule heating) in the wires and components during the charging process. 5. **Conclusion:** - **Statement 1** is true: The energy stored in the capacitor is indeed less than the energy provided by the battery. - **Statement 2** is also true: The energy loss due to heat explains why the energy stored in the capacitor is less than the energy supplied by the battery. ### Final Answer: Both statements are true, and Statement 2 provides the correct explanation for Statement 1. ---
