hree capacitors and a battery. In which of the following combinations of the three capacitors will the maximum possible energy be stored when the combination is attached to the batt - combinations will store the same amount of energy allel

Two separate capacitors, C1 and C2 C1 = 36 micro-Coulomb on 3 micro-Farad   C2 = 72 uC on X uF, X = 3.5 , if zero X =2   C2 had a gap of 0.2m maintained by a compressed plastic spring inside the gap, the natural spring length was 0.5m, the compressed spring length was 0.2 m. Spring constant = 8,000 micro-Newton/ meter Action: Connected the two capacitors in parallel Part A Find Q2-new, C2-new, new gap   Part B Find the initial total energy, the final total energy

If three unequal capacitors are connected in series, what can we say about the equivalent capacitance of these capacitors? It is greater than any of the individual capacitances. It is less than any of the individual capacitances. It is somewhere between the largest and smallest capacitances. We can't determine anything without knowing the values of the individual capacitances.

A simple adjustable parallel-plates capacitor is shown below. The plates have a radius of 8.0 cm and they are separated by a gap of 0.50 cm with nothing in between them. (a) Calculate the capacitance of this capacitor. (b) Calculate the charge stored when a battery of 9 V is connected to the capacitor. (c) Calculate the energy stored in the capacitor. (d) While the battery is still connected to the capacitor, a 0.50 cm-thick piece of wood (dielectric constant ? = 4.0) is inserted into the gap between the plates. Describe and explain what would happen to the capacitor’s voltage, to the capacitance, and to the stored charge.
