A device to store electrical charge is called :
A device to store electrical charge is called :
Open in App
Solution
The correct option is C Capacitor
A capacitor is a device for storing charge. It is usually made up of two plates separated by a thin insulating material known as the dielectric. One plate of the capacitor is positively charged, while the other has negative charge.The charge stored in a capacitor is proportional to the potential difference between the two plates. For a capacitor with charge Q on the positive plate and −Q on the negative plate, the charge is proportional to the potential:
If C is the capacitance, Q=CV.
