Superposition 叠加

Linearity 线性

Suppress 镇压；使什么止住

The principle of superposition is another name for the additivity property of Linearity: $f(x_1 + x_2) = f(x_1) + f(x_2)$

To solve a circuit using superposition:

1. Suppress all power sources

   To suppress a voltage source, replace it with a short circuit. (replace it with conductive wire) To suppress a current source, replace it with an open circuit. (cut wire off)

2. Analyze the resulting simpler circuits individually.

3. Calculate the sum of individual results.
