Can you explain how to connect a type 7812 voltage regulator ic?

A Type 7812 voltage regulator ic (integrated circuit) is 3-terminal device with separate pins for Input, Output and Ground.
Basically you connect a suitable source (a battery or a power supply unit that plugs into the house's main electricity service) to the Input pin and the Ground pin. Connect your load device (the equipment which requires a regulated voltage) to the Output pin and the Ground pin.
You can find circuit diagrams for using this type of voltage regulator IC in electronics textbooks and often in the catalogs produced by suppliers of electronic components.
For technical and licensing reasons circuit diagrams cannot be included within the answers on this site.

Function of integrated circuit 7812 in clap switch?
The 7812 is a 12v DC regulator that takes an input volt up to 44v and outputs 12v ( i believe there can be a 32v between the input and the output so 12+32=44 but check the data sheet). So to answer your question the 7812 is a voltage source that more than likely powers the rest of the circuitry in the clap switch, such as the relay, amp for microphone and any other devices.
What is the Maximum current can be used for transistor 7812?
1.5A
What resistor makes 10v into 5v?
You can't use one resistor to bring a voltage down, you have to use two in series in a voltage divider configuration, that is two resistors of the same value in serie between positive and negative, then you will have 5V between negative and the point between the resistors, any value can be used depending on the current jou are going to draw, note: you can not use to small a value at least 1K or up, if the value is to small the resistor will get to hot and it can burn out or it can burn your power supply or you can simply use a 7805 voltage regulator chip, it is inexpensive and easy to use, it only have 3 pins 1 = input, 2=GND and 3 is your output, one can get it in many deferent voltages 7803,7805, 7808, 7812 etc. Note: you can even adjust the output voltage between 5V and the RMS value of your power supply, by connecting a pot between GND and the center pin of the regulator, a smoothing cap is needed between GND and the input and one between GND and the output 1 to 10 mf 16V

A 7812 transistor is pnp type?
The 7812 is not a transistor. It is an integrated circuit, a voltage regulator designed to regulate an input voltage down to 12 volts output. It typically comes in a TO-220 case, and has three leads, so it sure does look like a transistor though!
Use of transistor 7812?
7812 is not a transistor. It is a three lead voltage regulator integrated circuit. Its maximum input voltage should be near 35 volts. The minimum input voltage should be near 14 volts. The output will be 12 volts.
How voltage stays constant in a closed electrical circuit?
A voltage regulator. Examples are the 78dd series of regulators where dd is the voltage, e.g. 7805, 7812. These work with a positive rail, the 79dd regulators work with a negative rail.
Explain the pin dia gram of IC 7812 belonging to category of logic gates?
The 7812 is not a logic gate. It is a three terminal voltage regulator with an output of +12V.Looking at the pins of the TO-220 device, with the flat side down, the left pin and the case is common, the center pin is input,and the right pin is output. For the smaller TO-92 78L12 device, the left pin is output, the center pin is common, and the right pin is input
Function of ic 7812?
it is ic of 78 series.its voltage is 12V
Use of ic regulator?
To regulate a powersupply. The variations of voltage will be nullified by this ic. For example a three legged ic say number 7812 gives 12v dc supply if you are applying a voltage of 13 to 24vdc at a maximum current rate of 1 ampere. If applied voltage is 24v the dissipation will be approximately 12w.
Function of integrated circuit 7812 in clap switch?
The 7812 is a 12v DC regulator that takes an input volt up to 44v and outputs 12v ( i believe there can be a 32v between the input and the output so 12+32=44 but check the data sheet). So to answer your question the 7812 is a voltage source that more than likely powers the rest of the circuitry in the clap switch, such as the relay, amp for microphone and any other devices.
What is the main use of ic 7812?
Here is circuit 9V power supply regulator with battery 12V backup system. Use IC 7812 and 7805 control voltage output by R3 1K output 9V 1A max. This is a 9V power supply which will work even on power failure. It uses a rechargeable battery and regulators. A transformer with 15-0-15 AC volts output is required. In the first regulator U1 the output is lifted up by 1.4V and in the second regulator U2 by a resistor divider. In the second regulator the voltage across resistor R3 is 5V, so the current is 5V / 1K = 5mA this adds to the quiescent current of 5mA from the regulators ground terminal and flows into the resistors R1 and R2 in parallel which form 404 ohms, 10mA thru 404 ohms is 4V. So the output will be 5 + 4 = 9V. Note that the charge and discharge paths of the battery are separated with diodes.
What is operation of IC 7806?
this is the voltage regulator IC which gives you +12 volts. after the capaciter it is being used in power supply.In 7812 , the 78 denotes (+ve) while 79 denotes (-ve) i.e.7912 provide you -12 volts. thelast two figure shows the output voltage.
