6 FAQs about [Solution of capacitor capacitance]
How do you solve a circuit with a capacitor?
For example: The voltage across all the capacitors is 10V and the capacitance value are 2F, 3F and 6F respectively. Draw and label each capacitor with its charge and voltage. Once the voltage and charge in each capacitor is calculated, the circuit is solved. Label these information in the circuit drawing to keep everything organized.
What is capacitance C of a capacitor?
• A capacitor is a device that stores electric charge and potential energy. The capacitance C of a capacitor is the ratio of the charge stored on the capacitor plates to the the potential difference between them: (parallel) This is equal to the amount of energy stored in the capacitor.
