**Capacitance and Temperature Coefficient Problems** A vacuum capacitor with dimensions \( A = 30 \, \text{cm} \times 50 \, \text{cm}, \, d = 4.00 \, \text{cm} \) is partly filled with a dielectric slab of thickness \( 3.00 \, \text{cm} \) and dielectric constant \( k = 12 \). **Problem 15:** Determine the capacitance of the capacitor. *Diagram Explanation:* The diagram shows a capacitor with a dielectric slab inserted. The slab covers part of the separation between the plates. **Problem 16:** If 50 Volts is applied across the plates, calculate the total energy stored in the capacitor. --- When the temperature is increased from 130°C to 200°C, the resistance of a resistor changes from 45 ohms to 69 ohms. **Problem 17:** Calculate the temperature coefficient of the resistor. **Problem 18:** Find the resistance at 20°C, denoted as \( R_0 \). *Hint:* Set up a system of equations and solve for these quantities.
