1. Tone generator circuit using 555 timer Bird sound generator, Ambulance Siren Generator These are some circuit diagrams of the sound generators. Sounds are like Bird sound, Ambulance siren, Beep Horn, and other different types. Use 9 to 12v Dc supply and components value should be the same as suggested in the diagram because any variation of components value can change the sound type. By some changes of values of some components as given below in the diagram, you can produce many different type of sounds. Use a medium-size speaker, These circuits can be useful for the making of Ala
2. why ac current passes through capacitor but dc can’t how capacitor block dc current Explanation 1 We try to understand using a discharged battery in the circuit. When switch on, the battery is starting to charge and increasing the voltage level of the battery and there is a flow of current. When the battery gets fully charged and the voltage of a battery increase and is equal to supply voltage then there is no flow any current between them. Let us consider a simple circuit as given below. In this circuit, a capacitor is connected with a resistor in series. A 12v DC
3. Comparator A comparator is a circuit that compares two input voltages or currents and gives output High or Low as per input signal. The Output is a digital form according to the input signal compared with the reference. Basically a comparator is used in electronics to compare the two Analog input signals given on both input terminals and we get the Digital output as High level or Low level. Comparator is used to sense the signal of a predefined rich level. If I set a level to sense then I can use a comparator to sense it when the input signal of this level cross more or below the leve
4. What is ohm’s law In the electrical field, Ohm’s law is a very important topic. This law is asked in almost all interviews and as basic fundamentals of electrical engineering for all who related to electrical engineering. This is a very important fundamental law that describes the Relation between Current, Voltage, and Resistance. There are three main quantities present in Electricity. An electrical circuit is made by these three Quantities Current (I), Voltage(V), and Resistance(R). There is no imagine the electrical circuit without anyone thing of them. And one other essential quant
5. you connect the circuit before the starter, i mean the supply to the motor starter pass through this circuit Relay. You start the motor using start switch ,when tank will full, then automatic stop the motor.
6. Zener diode working Zener diode Zener diode is a type of diode which flow of current also in reverse bias and in applications it always connected in reverse bias and zener diode limit the voltage, this diode is used for regulating the voltage in any circuit. It always works in zener breakdown voltage. Zener breakdown voltage is voltage level at this zener diode starts the current conduction in reverse bias. When reverse voltage increases then current conduction starts at a level, this level of voltage called breakdown voltage and the current flowing through diode is called zener curren
7. Semiconductor P-N Junction Diode Working Principle Diode is the two terminal polarised electronic semiconductor device . One terminal is Anode(-) and other is Cathode(+). The cathode is marked with the silver colour or colour band. This is the simplest semiconductor device but this is very important and most useful in electronic circuits. Diode Function The main function of the semiconductor diode is the flow of electrons to totally in only one direction across it . It means Diode conducts current in only one direction. If change the polarity of diode then no an
8. What is impedance (circuitspedia.com) Impedance (Z) is similar to Resistance (R) . Impedance and Resistance both oppose the current in circuit. Both are almost the same thing , But resistance related to DC Circuit. Resistance oppose the steady electric current in DC circuit. Resistance remains same (constant) at any different frequency range. Impedance is related with AC circuit. Impedance vary according to changing the frequency, this is not constant at different frequency range. Impedance also includes reactance (Inductive and capacitive property of the circuit)
9. LOGIC GATES Logic gates are the basic building elements of any digital systems or circuits. The name Logic gate is derived from the sense of the making decisions ability of such a device, and after making decisions it produce one output result. We can say that Logic gates are the fundamental building blocks of any digital circuits or digital systems. There are 3 basic Types of Logic gates – (1)-AND , (2)-OR , (3)-NOT Basically Logic gates are elementary electronic logic circuit that can make a variety of different types of circuits by interconnection of these three gates to p

11. In this project, a complete design and development procedure of a digital thermometer has been discussed. The algorithm used in this design is simple and easy to understand. The components used are limited and readily available in the market. Although the overall development of this project is lowcost and easy still the results are extraordinary. Let’s see how this design works. Arduino and LM35 based digital thermometers can be developed at home with very few components and instruments needed. Arduino UNO used in this design is a microcontroller which is responsible for data handling and
12. ----------------------------------------------------- This Inverter circuit is given from a trusted youtube channel on the robotics. He is showing in video on breadboard using this circuit. As name this is a simple inverter, so how this can powerful and regulated ???? Output Power is Also Depend on Transformer Ampere. In text also advised to use minimum of 1 A Transformer, not only 1 A Your corrected circuit is correct but my circuit is not wrong. One BD140 PNP transistor was also connected as here on that video.
13.  This circuit is 100% working. This is simplified diagram

No Any Direct Supply given on ic , Resistor is used

volume control connection is right. Check again

Which inverter circuit is wrong, tell me .

I will modify if any wrong

1. The volume control in your amplifier schematic is backwards. When it is turned down then instead of simply making a voltage divider with the signal, it shorts the input signal's high frequencies to ground but allows very low frequencies to be amplified.

2. This diagram is only for instructional. These common matters are understand by reader.
