Definitions:

Total Capacitance

The sum of individual capacitances in a circuit when connected in parallel, reducing when capacitors are in series, affecting the circuit's ability to store charge.

μ F

Microfarads, a unit of capacitance equal to one millionth of a farad.

Parallel Connection

A way of connecting electrical components in a circuit so that each component is directly connected to the voltage source, and the current can flow along multiple pathways.

Total Capacitance

The overall capacity of an electrical circuit to store an electric charge, often measured in farads (F).
