Proteus series 46 thermistor will display rv value, because this version is equipped with rv value detection device, which can very sensitively sense the thermistor value of each prpteus product, which is very fast and convenient.
This element is called a potentiometer. Although the principle and graphic symbol are the same as rheostat, it can also be used as rheostat under the condition of small current, but its main function is to adjust the potential of a certain point in the circuit. So it allows very little working current and power. In this circuit, it is used to adjust the potential of some poles of the integrated block.
Right-click the display element, select the Attribute Editor, and find the option of "Display Text" in the Attribute Editor, and set it to "{RV 1}" (where RV 1 is the name of the rheostat). Connect the circuit, simulate and open the display screen, and you can see the resistance value of the rheostat displayed on the display screen.
Where Rv is the resistance of rheostat and Rf is the resistance of constant resistance. According to ohm's law, the thermal power P in the resistor can be expressed as: p = I 2 * r, where I is the current in the circuit. Our goal is to find a resistance value to minimize the total thermal power in the circuit.
RV 1 is an ammeter, which is used to measure the current in AC and DC circuits. In the circuit diagram, the symbol of ammeter is circle A. Current values are expressed in amperes or standard units. An ammeter is made according to the action of magnetic field force in a magnetic field on a charged conductor.
The feedback coefficient of the circuit varies with frequency, which has the characteristic of frequency selection (for convenience of analysis, it is assumed that the capacitance reactance at high frequency is 0).
Proteus resistance name
Resistance is called resistance in proteus. Resistance is a physical quantity, which physically represents the resistance of a conductor to current. The greater the resistance of a conductor, the greater the resistance of the conductor to current. Different conductors generally have different resistances, and resistance is the nature of the conductor itself.
In Proteus, 5 10R resistors are generally named as "R_5 10, R5 10, R510Ω, etc. Where "R" stands for the abbreviation of the English word "Resistance", "5 10" stands for the resistance value, possibly followed by the Greek letter "ω", indicating the unit ohm.
The name of the resistor in the simulation software is "cap-pol". Take proteus software as an example, open proteus software on the computer and wait for the loading to be completed. After entering the main interface of the software, click the "P" button.
This photo of you was drawn by multisim software. Resistance in proteus is not this symbol, but the effect is the same, both of which are internationally used. The component code of resistor in proteus is resistor. There are resistors with various resistance values and power W numbers in it.
Ldr. Click P on the schematic diagram, place the component, and enter LDR in the keyword column. Two photoresistors, LDR and LDR torch, will appear in the table. Look at you using that.
How to use proteus sliding rheostat
1. First, after opening proteus software, click the P button to enter the equipment library, as shown in the figure below, and then enter the next step. Secondly, fill in POT in the keyword, select resistance as the category, as shown in the figure below, and then go to the next step.
2. The left component is called pot, and the middle and right components are pot -HG, which can be adjusted.
3. As shown in the figure below, the resistance of the sliding rheostat is 200 ohms, adjusted to 20%, and the effective resistance is 40 ohms. According to the measured current of 0.25A, the calculation result is correct.
Where is the Schmidt trigger in proteus7.8?
In electronics, Schmitt trigger is a comparator circuit with positive feedback.
Schmitt trigger has two stable states, but different from general trigger, Schmitt trigger adopts potential trigger mode, and its state is maintained by input signal potential; Schmidt trigger has different threshold voltages for negative falling and positive rising input signals.
Schmidt trigger is a kind of shaping circuit, which can shape a voltage waveform with slow edge change into a rectangular pulse with steep edge. Compared with ordinary flip-flops. It has the following characteristics: (1) has two stable states, but it has no memory function, and the output state needs corresponding input voltage to maintain it.
Schmitt trigger composed of CMOS gates is shown in Figure 2. In the circuit, two CMOS inverters are connected in series, and the voltage divider RR2 feeds back the voltage at the output end to the input end, which affects the circuit.
Schmidt trigger circuit and its working principle are described in detail. Schmidt trigger is a kind of motor control circuit, which can automatically adjust the current of the motor when the motor is running to maintain the speed of the motor. Its working principle is to maintain the set speed of the motor by monitoring the speed of the motor and adjusting the current of the motor.
