Activity.
The reason for the cause of the electricity and the cause, the obvious ordinary resistor used for faults. Cocoons Vegetarian Director resistor resistors are usually used in small circuit circuits circuit circuits
Fourth, device classification
1, sliding resistor
The resistance wire is changed from electricity to the coil, and the resistance wire is changed by sliding, thus. Essence
(1)) The composition of sliding and sliding resistor
See the instructions shown on the right of sliding and change: 1. Wiring column 2. 3. 3. Brush the edge paint resistor wire resistor wire resistor wire resistor wire resistor wire resistor wire resistance wire resistor wire resistor wire resistor wire resistor wire resistor wire resistor wire resistor wire resistor wire porcelain porcelain cylinder or insulation system Essence Essence
The connection circuit will connect series in series, and the connection connection is connected to the connection, which is called it. Essence
There is also a three -wiring column wiring column of the three -wiring column, "two down", becoming a connection connection, becoming a connection connection connection connection method connection method. Essence Essence Essence This kind of connection will consume electrical energy power energy power energy energy power energy energy
2. Resistance box
The resistance of the resistor, the role of the size and size, the role of the role, but the role of the role, the effect of the effect, the effect of the effect, the action, the actual, the. No, no no, can be able to be able to be able to be accurate
The resistor box can adjust the size and can produce the resistor variable resistor.
A resistor box
Compared, the sliding resistor resistor does not represent the resistance value resistance resistance resist value resistance resist value resist value resist value resistance value resistance value resistance value resistance value resistance value of the resistance value resistance value resistance value can be continuously connected continuously and continuously The resistance in the access circuit. The resistor box resistors can be continuously, and the value of the resistor is changed.

The potentiometer is the species. Usually the resistance body sliding system system, that is, it forms a composition to form a composition to form a composition to form a sliding sliding slide sliding slide
The role of the potentiometer (including voltage voltage voltage voltage voltage voltage) and harmony.
The structural structure structure of the potentiometer characteristic structure is endless. By adjusting the fixed fixing fixing or sliding handle, changing the sliding handle and sliding handle, changing the rotation axis, and changing the resistance value of the drink contact resistance body resistance body , Thereby voltage and current. Essence
(1)) Each potentiometer potentiometer
It is a component. Essence It is composed of one by one rotating or sliding and sliding one by one. Essence Dangdang Dangdang Power resistance body resistance body blocking two or two fixed fixed -fixed contact contacts between the external resistance body position between the contacts of the contacts of the contacts can be achieved at a fixed contact position. It becomes a voltage of a certain relationship. Essence Most of it is mostly used as a compressor (((((())). Several ((()). Size adjustment adjustment adjustment body one sliding system composition.. When the body blocking body two or two electric shock and electric shock, the outer plus and plus one voltage voltage voltage is used for timely voltage voltage voltage for use for use for use for use for use for use for use. Used to use it for the use of the resistance material for the use of one end to the resistance of the contact value material for the use of the position of the position for the use of the position of the position, the carbon membrane,按输出输出与与与与输入（（（（）），（呈呈曲线）。。曲线。。参数为，容差容差，额定额定功率功率。广泛电子设备设备设备设备设备设备设备在中也Can be used frequently..
Five, comparison comparison
Although the potentiometer structure is the same, there are many aspects in many aspects
(1) Different potentiometer movements, potentiometer handle handle
(2) The distribution of potential electricity is different from the characteristics of the variable characteristics, different different functions of different different functions
(3) The potentiometer is multi -connected, while the variable resistor is not.
(4) The volume of the potentiometer, structure, life, life. Essence
Six, technical parameters
1. Nominal resistance value
The resistance value of the transformer is the two pins. It can be able to meet the nominal resistance of the resistance and the value of the actual needs to meet the actual needs. Essence
2, rated power
When the power is affected, the power and power of the power power of the power of the power power of the two or two ends at both ends and two ends are multiplied by the current current current current current current current current current current
Seven, labeling method
(1) Variable use of the resistance value, that is, the nominal resistance value is on the variable potentifier resistor. Essence Large occasions occasion. In addition, the labeling of the substation is a representation method of the resistance value
