To convert electrical energy to light, heat, or movement, an electrical circuit must have resistance. Resistance is an inherent obstacle to electron flow in conductors. Types of resistance: Four main types of resistance forces are, Friction: Friction is the force that prevents solid surfaces, flui...

Let us briefly review the properties of the four forces before we return to the unification attempts. The four forces of nature show a large variation in properties, their effective range and strength.This is a preview of subscription content, log in via an institution to check access. Preview...
解析 B。四个力合成时,通过调整方向,可以使合力接近最小,当 1N 和 4N 的力方向相反,2N 和 3N 的力方向相反时,合力最小,为 4N-1N-(3N-2N)=2N,但是题目中说四个力在不同方向,通过力的合成的平行四边形法则分析可得合力大于 2N,但是接近 2N,选项中最接近的是 1N。

The resistance of the electrode and lead materials is a contributing factor, and losses occurring within the dielectric material itself also occur and are often dominant. The relevance of ESR to capacitor selection is twofold: 1) it influences the AC response of the capacitor, and 2) it ...
