Terminal charge意思

"Terminal charge" is a term used in physics, specifically in the context of electromagnetism and electrical circuits. It refers to the charge that is accumulated at the terminals of a device, such as a capacitor, an inductor, or a conductor.

In the case of a capacitor, the terminal charge is the charge that is stored on the plates of the capacitor. The amount of charge stored on each plate is equal but opposite in sign, so the total charge at the terminals is the sum of the charges on each plate. The terminal charge is proportional to the voltage across the capacitor and is given by the formula Q = CV, where Q is the charge, C is the capacitance, and V is the voltage.

In an inductor, the terminal charge can refer to the current flowing through the device, which can be thought of as a flow of charge. The current through an inductor is not constant and can change with time, but at any given moment, the amount of charge at the terminals is the product of the current and the inductance of the coil.

In the context of electrical circuits, the terminal charge of a device can also refer to the net charge on the terminals of a conductor or other electrical component. This charge can be positive, negative, or zero, depending on the electrical properties of the device and the configuration of the circuit.
