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 voltage of a blender?
The blender itself has no voltage. It's designed to operate best and last longest
when it's plugged into an outlet that supplies a specific voltage, depending on
the country where the blender is marketed. In the US, that's around 120 volts AC.
If the blender will be sold in other countries, it may be designed for different voltage.
What prevents electricity from leaking out of wires in a circuit?
Because electricity must be conducted in order to move. It is not a liquid.
Is the resistance value of the resistor 22000 ohms 22 megohm resistor?
22Kiloohm is 22,000 ohms
22megohm is 22,000,000 ohms
Kilo is a thousand
meg/mega is a million
How can loading effect affect voltage measurement in a circuit?
Suppose you have two 100 kilo Ohm resistors in series across a 12 volt supply.The expected and actual voltage at their junction is 6 volts. Now measure the voltage across one resistor with a Voltmeter. The instrument must take a little power to move the meter needle or be taken by the digital circuitry. If the input resistance of the voltmeter is 100 Kilo Ohms then it will make that resistor under test appear to be 50 Kilo Ohms. The voltage across the resistor drops to 4 Volts. This is the loading effect of the voltmeter.
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.
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
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.
In what year was the intergrated circuit developed?
in what year was the integrated circuit developed?
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.
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 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
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 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.
What is the maximum voltage and current optical fiber can take?
Optical fibers transmit light, not electrical energy.
