15. Find the capacitance of the capacitor. 16. If 50 Volts is applied across the plates, what's the total energy stored in the capacitor? [Diagram] The diagram represents a parallel plate capacitor with the following dimensions: - The separation between the plates is 3 cm. - The area of one of the plates is 4 cm by an unspecified length, represented with hatching. - A dielectric material "K" is placed between the plates. When the temperature is 130 degrees C, the resistance of a resistor is 45 ohms. When the temperature is increased to 200 degrees C, the resistance increases to 69 ohms. 17. Find the temperature coefficient of the resistor. 18. Find the resistance at 20 degrees C, \( R_0 \). *Hint: Set up a system of equations, and solve them together.*
