练习 1解方程z-2iz-5=0. 2求z=(1+i)的值 3证明三角形的内角和等于π

We assume=Im cos(t+a)i=Im cos(ot+B) The phase angle by which the voltage leads

Let us assume a solution i(t=Ae, where a and S, are constant to be determined

Ohm's law states that voltage across many types of conducting materials is directly proportional to the current flowing through the material. U= Ri or R= i R--resis tance()( linear resistor) The resistor is a passive element that cannot deliver power or store energy

In the chapter we shall study the properties of second-order circuits, i.e., circuits containing two energy-storage elements. Such circuits will, in general, be characterized by second-order differential equations
