Capacitor Circuit Calculations - How to Find Charge, Energy and Voltage

In summary, a student is seeking help with a college assignment that involves calculating charge, energy stored, and voltage for different capacitors in two separate circuits. They are also asking for guidance on how to find the answers rather than being given the answers directly.

Not sure If I posted this is the correct place -Im new

hi, I am working on a college assignment. I'm on a day release program and unfortunately I missed the day where we covered this part. Please could someone help me?


The questions I need to answer are:

a) For each capacitor shown in figure 12 determine the charge, energy stored and voltage across EACH capacitor.

Figure 12 is:

200V DC series circuit with 3 capacitors C1 = 4 μF C2= 8 μF C3 = 10 μF


b) (same question different diagram)

Figure 13 is:

100v rail with two capacitors in parallel.
C1 = 12 μF
C2 = 2 μF



I have no Idea even on where to start.

If someone could help me out here I would be very great full, When I say help me out, I don't mean tell me the answers, more tell me how to find the answers.

Thanks

Grand

ifyou have 3 capacitors in series do you know how to calculate the combined capacitance? (I got 2.1μF)
Can you then calaculate the charge?
Do you know how charge is distributed amongst capacitors in series?
Hope this gets you going
 

FAQ: Capacitor Circuit Calculations - How to Find Charge, Energy and Voltage

What is a capacitor?

A capacitor is an electronic component that stores electrical energy in the form of an electric charge. It is made up of two conductive plates separated by an insulating material, known as the dielectric.

How does a capacitor work?

When a voltage is applied to a capacitor, it creates an electric field between the two plates. This causes one plate to accumulate a positive charge and the other to accumulate a negative charge. The capacitor can then store this charge until it is discharged.

What is the purpose of a capacitor in a circuit?

Capacitors are used in circuits to store and release electrical energy. They can be used to filter out unwanted signals, stabilize voltage levels, and store energy for later use.

What are the different types of capacitor?

There are many different types of capacitors, including ceramic, electrolytic, film, and variable. They vary in size, capacitance, and voltage ratings, and are each suited for different applications.

How do you calculate the capacitance of a circuit?

The capacitance of a circuit can be calculated using the formula C = Q/V, where C is the capacitance in Farads, Q is the charge in Coulombs, and V is the voltage in Volts. The capacitance can also be determined by the physical characteristics of the capacitor, such as the distance between the plates and the dielectric material used.
