教你一手稳恒电路中,电流不随时间变化,相应地,导体内部有一稳恒电场,电荷在电场力作用下做定向移动消耗电场能,电源中非静电力做功,将其他形式的能转变为电场能,这是稳恒电路的基本情况.各种形式的电路有一些共同的基本规律,例如欧姆定律.焦尔定律,基尔霍夫定律,从这些基本规律出发,抓住电路的特征,才能完成对一个电路的计算.先介绍一段含源电路的欧姆定律.在电路计算中,常须确 Teach you a stable circuit in one hand, the current does not change with time, accordingly, the conductor has a steady electric field inside, the electric charge under the action of the electric field to do the directional movement of the electric field, power non-electrostatic power to work, the other forms can be transformed into Electric field, which is the basic situation of the steady circuit.A variety of circuits have some common basic law, such as Ohm’s law.Joule’s law, Kirchhoff’s law, starting from these basic rules, grasp the characteristics of the circuit, In order to complete the calculation of a circuit.First introduce a Ohm’s law with the source circuit.In the circuit calculation,
