Capacitance is one of the central concepts in electrostatics. Understanding its meaning and the difference between its definition and the ways of calculating capacitance can be challenging at first. This tutorial is meant to help you become more comfortable with capacitance. Recall the fundamental formula for capacitance: C = Q/AVC, where C' is the capacitance in farads, Q is the charge stored on the plates in coulombs, and AVC is the potential difference (or voltage) between the plates. In the following problems it may help to keep in mind that the voltage is related to the strength of the electric field E and the distance between the plates, d, by AVc = Ed.

Imagine that two parallel plates are charged to achieve a voltage difference Vo between the plates. They have area A and spacing d. The plates are then electrically isolated so that no charge can be added or taken away. A good conductor of thickness d/2 is placed in between the two plates, as shown. What then is the capacitance of this new configuration? Is it different from the original capacitance?
I keep getting different answers with each calculation and unsure of where I am going wrong. If possible, please show steps so I may understand where my calculations were incorrect. (a). What's the capacitance of your capacitor? (the value and unit(s)). (b). If you disconnect the battery and separate the plates to a distance of 3.50 cm without discharging them, what will be the potential difference between them? (the value and unit(s)).
A capacitor of capacitance 14 mF is connected across a battery providing potential difference of 3.5 V. What is the absolute value of the charge on each plate of the capacitor? Provide your answer in milicoulombs, with a precision of one place after the decimal.
Answer is in volts. Do I use the potential difference formula here, or voltage due to a point charge? I'm feeling lost on where to begin. It'd really help to see this worked out. Thank you
For the circuit shown, AVbattery = 28 V, R₁ = 5.0 02, R₂ = 5.0 2 and C= 4.5 F. The capacitor is initially uncharged and the switch is open. What is the charge on the capacitor a long time after the switch is closed, in Coulomb? Your answer needs to have 2 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement. R₁ www R₂ www C
Two identical capacitors (A and B) with capacitance Co are hooked up to a battery of voltage Vo. A dielectric of constant ko is added between the plates of capacitor B while it is connected to the battery, as in the figure at right. a) Is the charge on capacitor A (QA) greater than, less than, or equal to the charge on capacitor B (QB)? What about the voltages (VA and VB)? Explain your reasoning. b) Vo CB The capacitors above are carefully disconnected from the battery (without being discharged), after the battery is disconnected the dielectric slab is removed from capacitor B. The capacitors remain connected to each other the entire time. Determine an expression for the final charges on each of the capacitors (QA₁f and QB₁f) after the dielectric has been removed in terms of the given constants (Ko, Co, Vo). Show your work and explain your reasoning.

Electrostatic forces are conservative. This means that mechanical energy (KE +PE) is constant or conserved in absence of other dissipative forces such as friction. If a charged particle moves from point A to point B in an electric field (assume that dissipative forces such as friction are absent), select all the statements that are true. The symbol A represents the change in the particular quantity. Recall what does positive and negative work mean? Reflect on what the negative sign represents in each case? Select multiple answers. APE=-Work A→B i.e., for positive work, PE decreases and for negative work, PE increases ΔΚΕ # -ΔΡΕ ✓ changes in KE and PE are not connected. ΔΚΕ = -ΔΡΕ i.e., if KE increases, PE decreases and vice-versa APE=WorkAB Ⓒi.e., for positive work, PE increases and for negative work, PE decreases
A spherical capacitor consists of an inner spherical shell of radius R1 and an outer spherical shell of radius R2, as shown above. Our goal is to calculate the capacitance of this configuration of electrodes.To start, suppose the inner sphere has a charge +Q and the outer sphere an equal but opposite charge -Q. Find the capacitance using the following steps:1. Use Gauss's law to find an expression for the electric field in the region between the two spheres.2. Find an expression for the potential difference between the spheres from the electric field (you'll have to integrate the electric field from the negative electrode to the positive one).3. Calculate the capacitance from C = Q / ΔV.Suppose in this case that R1 = 2.00 cm and R2 = 4.30 cm. What is the value of the capacitance?
Note: The value of a=0, b=5 and C=7.
