Circuits
Overachieving and under-appreciated, circuits are the foundation that our technological society is built on. Now's your chance to find out not only how they work, but why. Questions regarding the physics behind voltage, resistance, capacitance, inductance, transistors, LEDs, switches, and power supplies; and how they're used to create analog and digital circuits, should be directed here.

What is the Pin configuration of ic l78050 voltage regulator?
on facing the side having black cover ie the front side...starting from the left..
pin1:supply
pin2:ground
pin3:output
Handling precautions CMOS components?
IDK, i have to do this in tech, this is a difficult question.
To handle these components properly you need latex gloves, an extra large body suit.
and a trained professional. I happend to have all.
you need to carry the circut bored carefully, don<t even look at it, run with your eyes closed and your hands covering your ears. Some people will say different answers but this is the only correct way. Have three toes crossed on your right foot, and one on your left.
Scream the song Mary had a little lamb as your are running.
The tiny piece of silicon that houses millions of microminature electronic circuits is called a?
chip
According to Theremins theorem any linear active network can be replaced by a single voltage source?
You are confusing "Thévenin" with "Theremin." Léon Charles Thévenin (1857-1926) developed a theorem for linear electrical networks stating that any combination of voltage sources, current sources and resistors with two terminals is electrically equivalent to a single voltage source and a single series resistor.
If we increase the current then what about the power factor?
The power factor depends on the phase angle between the voltage and current
on a conductor. The amplitude of the current has no effect on it.
Is changing a blower motor resistor difficult?
Changing the actual resistor is dead easy. The hard part is gaining access to the resistor. Some vehicles need the dash assembly removed to gain access.
What is exactly the function of Neutral link in an electrical circuit?
To protect a circuit, we use a fuse or circuit breaker. The fuse or circuit breaker must always be placed in the lineconductor, never in the neutral conductor. So, if we want to completely isolate a circuit from the supply, we must remove the fuse from the line conductor, and open the link in the neutral conductor. A 'link' is a non-fusible metal break point in the neutral.
In what year was the intergrated circuit developed?
in what year was the integrated circuit developed?
It's Angle modulated system where the amplitude remains constant & frequency & phase varies with respect to modulating signal.
Why the resistance of PMOS is greater than NMOS?
because pmos has low mobility . the inverter threshold voltage can be shifted to the middle and the inverter is more symmetrical in terms of transistor times.
An analog-to-digital converter (abbreviated ADC, A/D or A to D) is a device that converts a continuous quantity to a discrete digital number. The reverse operation is performed by a digital-to-analog converter (DAC).
Typically, an ADC is an electronic device that converts an input analog voltage (or current) to a digital number proportional to the magnitude of the voltage or current. However, some non-electronic or only partially electronic devices, such as rotary encoders, can also be considered ADCs.
The digital output may use different coding schemes. Typically the digital output will be a two's complement binary number that is proportional to the input, but there are other possibilities. An encoder, for example, might output a Gray code.
An ADC might be used to make an isolated measurement. ADCs are also used to quantize time-varying signals by turning them into a sequence of digital samples. The result is quantized in both time and value
Positive logic in a logic circuit is one in which?
In Positive logic, we all assume that the more positive (binary) voltage state is One, the less positive voltage state is Zero.
Both voltage states could be positive, both could be negative, or they could be opposite polarities.
What is the maximum voltage and current optical fiber can take?
Optical fibers transmit light, not electrical energy.
What is Cut-off voltage in fet?
fet is a voltage controlled device...cut off voltage in fet refers to that voltage of the gate - source junction at which the current flow through channel is zero
Is voltage negative or positive?
A negative or positive sign is applied to a current depending upon the direction in which it is moving, and in the case of alternating current, that direction changes 60 times per second. Viewed strictly as a form of energy, voltage is always positive. So far, physics has not detected negative energy.
Do you use the same ground for amp and capacitor?
not to my knowledge you have to have a different one for each because they do not go to the same thing exactly its best to find one ground for each but use the same power
Is electric current a form of voltage?
No, electric current is the rate at which electrons flow in a conductor.
The voltage is what makes the electrons move. They have different units of measurement
It's a bit confusing and a bit of a cheat really
Electrons are measured in units called Coulombs. And one coulomb is the number of electrons passing when a current of one ampere (amp) is said to be flowing for one second. One coulomb is a lot of electrons about six million million million of them in fact. If a current of one ampere) is flowing for one second. all these guys will be passing by.
We like to think they are moving at the speed of light as when we flick the switch hey presto we can see the light.
However the electron in the Coulomb gang are a bit like Mario and they are all over the place and really each electron only move about a quarter of a millimeter in that same second.
So how come we see the light go on straight away? Well that the cheat. Electrons in a wire are packed in so if we add on in at one end we push one out at the other.
so for the Coulomb gangs if one gang is moving (because of the voltage - which we haven't come to yet) one gang is moving out.
Now if the current is an alternating current - because it's been made to behave that way because of an alternating voltage was made at the power station - our coulomb gangs are not moving very far at all. In fact in England the current coming into our houses is alternating backwards and forwards at about 50 cycles/second. So in that second the Coulomb gang - all six million million million of them making up our current of one amp go backwards and forwards about a quarter of a millimetre 50 times/second.
Getting back to your voltage.
Voltage is also known as potential difference or an old name is electron moving force and this is the condition we create at the power station or in a battery or through static electricity by creating a positive and negative choice for our electrons.
There are two common important relationships between voltage and current.
Power measured in watts = volts x amps
Resistance measured in ohms = volts/amps.
I could go on forever but remember you can't really have current without volts and you can't really have volts without current. The way they relate to each other depends on where we are and what we are doing.
Hope this helps

Why do electric circuits have to be complete?
if they're not then the circuit will not work and it won't be able to power wat u want it to power for example a lightbulb.it will be an open circuit
How much voltage comes from the pole to the house?
240 volts from the secondary side of the transformer to your house
What is the difference between the E12 and E24 resistor series?
E12 ( 10%): 10 12 15 18 22 27 33 39 47 56 68 82
E24 ( 5%): 10 11 12 13 15 16 18 20 22 24 27 30
33 36 39 43 47 51 56 62 68 75 82 91
The basic difference is that the E24 have "extra" values between those of the E12. It's roughly midway between the E12 points. They're more expensive too.
There's also an E6- it runs:
10 15 22 33 47 68
At the top end there's an E192- wildly expensive but extremely accurate. They're used in life-critical systems or super accurate industrial machines.
