In electrical engineering, the passive sign convention (PSC) is a sign convention or arbitrary standard rule adopted universally by the electrical engineering community for defining the sign of electric power in an electric circuit. [1]

2025年1月20日 · Pensacola State College is accredited by the Southern Association of Colleges and Schools Commission on Colleges (SACSCOC) to award baccalaureate degrees and associate degrees. Pensacola State College also may offer credentials such as certificates and diplomas at approved degree levels.

在电气工程中，无源符号约定(psc)是电气工程界普遍采用的符号约定或任意标准规则，用于定义电路中的电力符号。 惯例定义从电路流出到电气元件的电能为正，从元件流出到电路的电能为负。

被动符号规定 （英语： Passive Sign Convention），是一项符号规则，用于定义 电压 、 电流 和 电功率 的正负号。 [1] 一般而言，电功率的正负号是从 被动元件 （负载）的角度出发。 电流由正极流向负极代表负载，功率定义为正数。 相反，电流由负极流向正极，则代表 电源 或 主动元件，功率是负数。 [1][2] 不过，符号规定只在 科学 或 工程 计算中使用，生产商提供的标示牌或资讯并不需要遵守符号规定。 在日常生活中，无论是主动元件还是被动元件，几乎所有设备的功 …

2024年1月9日 · The passive sign convention is the same concept. It is an algorithm to decide what is adding potential energy to the system and what is taking it away. Here are some basic ground rules: All resistors are either positive or negative uniformly.

Passive sign convention deals with the designation of the polarity of the voltage and the direction of the current arrow in an element or a sub-circuit. The convention is satisfied

2023年4月25日 · With PSC, $U_C = q/C$ says that when the charge on the positive plate is positive, the positive terminal is at a higher voltage. Alternatively, with PSC, $I_C=C\frac{dU_C}{dt}$ says that if current is flowing into the positive terminal ($I_C>0$), the voltage difference between the positive and negative terminals is increasing. $\endgroup$ –

In electrical engineering, the passive sign convention (PSC) is a sign convention or arbitrary standard rule adopted universally by the electrical engineering community for defining the sign of electric power in an electric circuit.

For each device, state whether Passive Sign Convention (PSC) or Active Sign Convention (ASC) is used for the defined current and voltage. Then determine whether the device is absorbing or delivering power. Need a hint? Review the rules for determining whether something follows …
