In electrical equations, what does the letter C stand for?

In electrical equations, the letter C represents Farads, which is the unit of capacitance in the International System of Units (SI). Capacitance is a property of an electrical component, typically a capacitor, that indicates its ability to store an electric charge. A capacitor that has a capacitance of one Farad can store one coulomb of charge at one volt of electrical potential.

Understanding capacitance and the significance of the unit Farads is essential for grasping the behavior of circuits involving capacitors, such as timing circuits and energy storage applications. Capacitors are widely used in various electronic devices, and knowing how to calculate the capacitance in a circuit allows for the design and analysis of these systems effectively.
