图1中,输入设备选用的是按钮SB0的常闭触点,输入继电器X0的线圈状态取决于SB0的状态。该按钮未按下时,输入继电器X0线圈状态为“1”通电状态,程序中所有X0触点均动作,即常开触点接通,常闭触点断开;若按下该按钮,则输入继电器X0线圈状态为“0”断电状态,程序中所有X0触点均恢复常态。如果输入继电器连接的输入设备是...
内容提示: FeaturesIn spite of the numerous textbooks on circuit analysisavailable in the market, students often find the coursedifficult to learn. The main objective of this book isto present circuit analysis in a manner that is clearer,more interesting, and easier to understand than earliertexts...
Consider the electric circuit in the figure. This circuit is described by the system of differential equations ddt(IV)=([0,1L],[-1C,-1RC])(IV) Suppose thatR=4Ω,C=4F,andL=256H.Suppose also thatI(0)=5A andV(0)=984V.FindI...
When using Kirchhoff's circuit laws and Ohm's law to model the system of linear equations corresponding to an electric circuit (so far, circuits involving resistors and sources only), I haven't been able to find any circuit that yields an inconsistent system nor ...
由直流电机基本工作原理可知,直流电机无论作发电机运行还是作电动机运行,都必须具有一定强度的磁场,所以磁场是直流电机进行能量转换的媒介。因此,在分析直流电机的运行原理以前,必须先对直流电机中磁场的大小及分布规律等有所了解。 1.直流电机的空载磁场 直流电机不带负载(即不输出功率)时的运行状态称为空载运行。空载...
