不要把物理公式看作数学公式，请也尊重自然的经验法则。
Don't see the physical formulas as mathematical formulas, please also respect the experience rules of nature.

连接正负极 Connection of positive and negative poles

欧姆定律 Ohm's Law

\(I=\frac{V}{R}\)

物理: V电压 R电阻 I电流 Intensité(由法国物理数学家安德烈-马里·安培命名)
Physics: Voltage Resistance Intensité(intensity, electric current)(the current, named by André-Marie Ampère)

当\(R\approx 0\)(短路)(\(\approx\)大概是一个主要用于物理的数学符号)
When \(R\approx 0\)(short-circuit)(\(\approx\) must be a mathematical sign which is most used in physics)

\(I \to \infty\)(物理中的\(\infty\))
\(I \to \infty\)(\(\infty\) in Physics)

功耗 Power Dissipation

电路中耗散的功率（P）由下式给出：
The power (P) dissipated in a circuit is given by:
\(P=V\cdot I\)

所以 \(P \to \infty\)，会发热
So \(P \to \infty\), it heats

为什么在短时间内它不会损坏(自然现象) Why in a short time it doesn't damage(natural phenomena)

重新设置问题: 为什么在大约1-2秒之后正常连接, 半导体元件/电子元件/晶体管/导线依然功能完好？
Reformate the problem: Why after 1-2 seconds then correctly connected, will semiconductor components/electronic components/transistors/wires still function?

\(P=I^2\cdot R\)

因为阈值电流 Because of Threshold Current(\(I_{th}\))
