What is the ratio between the charge on either plates of capacitor and the potential difference between the plate?
The ratio between the charge on either plate of a capacitor (Q) and the potential difference (V) across the plates is given by the capacitance (C) of the capacitor, expressed as ( C = \frac{Q}{V} ). This means that the capacitance is a measure of how much charge a capacitor can store per unit of voltage applied. Therefore, the ratio ( \frac{Q}{V} ) is constant for a given capacitor and is equal to its capacitance.
How much resistance will an ohmmeter indicate across a good capacitor?
because resistance is restricting the current and voltage, so for it be accurate you need to know what the voltage and the amps are.AnswerCapacitance is quite independent of resistance and, therefore, it will NOT vary if resistance is changed.
If a 0.40-uF capacitor is connected to a 9.0-V battery how much charge is on each plate of the capacitor?
The units of capacitance are called farads. A one farad capacitor is a capacitor with 1 volt potential difference with 1 coulomb of charge on the capacitor, C = Q/V or Q=CV So the charge held on your capacitor is Q = CV = 9Volts * 0.40*10-6Farads=3.6*10-6 Coulombs
What is an importance of capacitance?
capacitor is a device to store charge .it is based on the concept that when the potential of the capacitor is decreased it can gain some more charge so Q = CV where V is potential and Q is the charge stored then C is the capacitance. capacitance is the ability of the capacitor to store charge. expression for capacitance is C=ɛA/d where ɛis permittivity and A is area of capacitor plates ,d is plate separation.
How much charge is held on one plate of a 15 farad capacitor brought to 6v?
The charge stored on a capacitor can be calculated using the formula ( Q = C \times V ), where ( Q ) is the charge in coulombs, ( C ) is the capacitance in farads, and ( V ) is the voltage in volts. For a 15 farad capacitor charged to 6 volts, the charge is ( Q = 15 , \text{F} \times 6 , \text{V} = 90 , \text{C} ). Therefore, one plate of the capacitor holds 90 coulombs of charge.
What happens to the charge if you double the voltage across a capacitor?
In order to double the voltage across a capacitor, you need to stuff twice as much charge into it.
Why is there a C in the equation for a discharging capacitor?
The C represents the capacitance (in farads) of the capacitor. It is a measure of how much charge a capacitor can hold. This is needed to know how much energy the capacitor is holding.

Why is capacitace inversely proportional to voltage?
Capacitance is not inversely proportional to voltage, rather capacitance is a measure of how much charge a capacitor can hold for a given voltage. The capacitance value remains constant regardless of the voltage applied across the capacitor. The relationship between capacitance, voltage, and charge is governed by the formula Q = CV, where Q is charge, C is capacitance, and V is voltage.

How are the terms capacitor and capacitance related?
Capacitor is the name of the device and capacitance is a measure of farads in the capacitor. Capacitance is the capacity for storing charge in the capacitor as measured in farads, micro farads or millifarads.
How much charge is held on one plate of a 15 farad capacitor brought to 6v?
The charge stored on a capacitor can be calculated using the formula ( Q = C \times V ), where ( Q ) is the charge in coulombs, ( C ) is the capacitance in farads, and ( V ) is the voltage in volts.

How does capacitance change with voltage?
Capacitance is a measure of how much charge a capacitor can store for a given voltage. As the voltage across a capacitor increases, the capacitance typically remains constant. However, in some cases, the capacitance may change slightly due to factors like dielectric breakdown or non-linear effects.
A farad is a measure of what?
The Farad is a measure of how much electric charge is accumulated on the capacitor. Named after Michael Faraday
How can you store a different amount of charge in a capacitor?
Power = V*I Power = (V) * (C*dV/dt) To store more / less power / charge, charge the capacitor with a greater / smaller voltage (make sure the cap is rated for at least as much as the voltage you are charging from, though).
