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(\(I_{th}\))
热力学：Thermodynamics：
温升:Temperature Rise: \(\Delta{T}\)
热阻:Thermal resistance: \(R_{th}\)
\(P=\frac{\Delta{T}}{R_{th}}\)
焦耳定律: Joule's Law
\(Q=I^2Rt\)
heat Q(/J(oule)), current I(/A), Resistance R(/\(\Omega\)),time t(/s)
So it will take some time to be damaged.
