Question

How much charge is stored in a capacitor?

Answer 1

Hint: A passive two-terminal electrical component used to store energy electrostatically is called a capacitor. There are various forms of practical capacitors but every form contains at least two electrical conductors. The electrical conductors are also called electrical plates which are separated by a dielectric. When a potential difference is applied across the two plate’s positive charge will be collected at one plate and the negative charge is collected on another plate.

Complete step by step answer:
We can calculate the charge stored in the capacitor using the formula,
\[Q = CV\]
Here, \[Q\] is the charge stored in the capacitors
           \[C\] is the capacitance of the capacitor,
           \[V\] is said to be the voltage applied across the capacitor.
The electric charge stored in a capacitor \[Q\] in coulombs is equal to the product of the capacitance of the capacitor \[C\]and the voltage in volts \[V\].

Additional Information:
When charges are accumulated in the plates of the capacitor creates a potential difference across the capacitor. The charge holding capacity of the capacitor is defined as the amount of charge accumulated in the capacitor. This charge holding capacity of the capacitor is called the capacitance of the capacitor. This total amount of charge accumulated in the parallel plate capacitor is directly proportional to the voltage developed across the capacitor.
\[Q \propto V\]

Note:We should note that even when the voltage applied to the capacitor is disconnected, the charge stored in the plates of the capacitor remains until we discharge the capacitor in some other way. This is a very useful aspect of the capacitor. This total amount of charge that is stored in the parallel plate capacitor usually depends upon the surface area of the plates.
