Devices such as power supplies and loads in circuits are circuit components. In a circuit, a component that cannot provide electrical energy is called a passive component. Passive components are further divided into energy-consuming components and energy-storing components, such as resistors; the latter such as inductors and capacitors. A battery, a generator, or the like that can supply electric energy in a circuit is called a power supply element, or is called an active element.
1. The resistance element resistance is a circuit element that reflects the current thermal effect. In an actual AC circuit, such as an incandescent lamp, an electric furnace, an electric soldering iron, etc., can be regarded as a resistive element.
(1) Definition of linear resistive element and non-linear resistive element. If a two-terminal element, the relationship between its current and its voltage across it, that is, the volt-ampere relationship (VAR), is a line passing through the coordinate origin in the u and i planes. The straight line, the slope of the line is the parameter resistance R of the component, in ohms (Q). This component is called a linear resistance component. If the parameter R of the linear resistive element is a constant that does not change with time, it is called a linear, non-time-varying resistive element. If the VAR of the resistive element is a straight line passing through the coordinate origin in the first and third quadrants on the 扒f plane, and the slope R of the straight line is a positive constant, it is called a linear positive resistive element. The resistive components referred to in this course generally refer to linear, non-time-varying positive-resistance components.
If the VAR of the two-terminal element is a curve that does not pass the coordinate origin on the u and i planes, such an element is called a nonlinear resistance element.
(2) Characteristics of Resistive Element The characteristic of the resistance element is that it exhibits resistance to charge movement and has a property of hindering current flow. The resistance R of a resistive element specifically exhibits this property. The characteristics of the resistive element can also be expressed by another parameter conductance, the conductance is represented by G, and the conductance is the reciprocal of the resistance R, ie

Conductance G represents the ability of the resistive element to conduct current in S (Siemens).
(3) Linear resistance element and Ohm's law linear resistance element. Since its parameter R is a constant, the voltage across the element is proportional to the current passing through it, called Ohm's law. In the associated reference direction as shown in Figure 1-4, the mathematical expression is
U= RI or I=GU (1-9)

WII U Pro Controller

Product Characteristics
1) This Controller is compatible with Wii U console and incompatible with Wii Console .
2) The Controller is connected to the Wii U console via Bluetooth wireless. Within the effective working distance of 8 meters, the signal is stable, no delay and no dropping.
3) No need to install any driver, the handle can be used when it is connected with the Wii U host.
4) This handle supports all functions of the original Wii U Pro handle.
5) Built-in motor to support vibration feedback function.
6) Built-in 400 mAh lithium-ion battery, which can supply power for less than 10 hours after full charge.
7) Built-in four LED channel indicator lights, which can be used to number players in the order of connecting to the computer.
8) Up to four handles can be connected to the host at the same time.
9) Ergonomic design, feel comfortable, even if continue to play games for several hours is not easy to fatigue.
10) Each handle is equipped with a USB charging data line for charging the handle.
11) When the handle is operated without any action, it goes into dormancy for about 5 minutes, and the indicator light of the handle goes out.
Product Use
1) Press the power button of the handle. If the four LED channel lights do not flicker, it means that the handle has no electricity and needs to be charged first.
2) Open the Wii U host and connect the necessary accessories, such as the display.
3) Open the handle: Press the power key of the handle, and the four LED channel lights will flicker quickly.

4) Press SYNC in front of the Wii U host, then SYNC on the back of the handle. An LED lamp on the handle will be long on, indicating that the code is successful and the handle can be used.
