Electronics Engineering
Electronics Engineering is a branch of engineering that deals with practical applications of electronic components, devices, systems, or equipment. Electronics are devices that operate on low voltage sources, as in electron tubes, transistors, integrated circuits, and printed circuit boards and use electricity as part of its driving force.

Assuming a perfect machine (doesn't have any internal resistance), an EMF of 45*35 = 1575 volts is required. Actual EMF required by the machine will include the voltage drop internal to the machine, so 1575V constitutes a minimum necessary value.
The charge in a capacitor is between the plates. The dielectric is only an insulator that allows the plates to be very close without touching and discharging the charge. There is no battery in a capacitor.
A signal has a frequency of 100 Hz and a phase of 180 degrees?
The wave has been offset from zero by 0.005 seconds
The value of the resistor has 5 volts across it and has 20mA flowing through it?
The value of a resistor with 5 volts across it and 20 milliamperes of current flowing through it is 250 ohms.
Ohm's Law:
E = I R
R = E/I
What is the relationship between a circuit and a circuit configuration?
circuit is a schematic which explains some operation using some symbols.
circuit configuration is giving a detailed explanation about its parameters
How do you make a jig for a cell phone to measure radiation for a science fair project?
i was looking for a pictuer of a jig to make for a hold a cell phone to measure radiation
How to design a phase shifter circuit using operational amplifier to have a desired phase shift?
There are many phase shift oscillator circuits on the internet. Google search, `phase+shift+oscillator+schematics` and `phase+shift+oscillator+diagrams`.
Generally, if you want to change the phase shift characteristics, you'll need to substitute some fixed resistors with variable resistors and depending where they're placed, you can either change the operating frequency or the waveform characteristics.
The invert level is the base interior level of a pipe, trench or tunnel; it can be considered the "floor" level. Conversely, the crown level is the highest interior level, and can be considered the "roof" level
Was there a movie buckle down winsocki?
The song is the big finale to the 1943 MGM film, BEST FOOT FORWARD, starring Lucille Ball.
The film is an adaptation of a Broadway hit about a boy at Perkiomen School, Pennsburg, Pa, who invites a Hollywood star to his big dance. The original writer credited with the Broadway screenplay, was John C. Holm, Perkiomen School class of 1912.
What is Ring Protection in SDH?
Ring protection is a system where multiplexers are connected in a ring topology. If a single span fails traffic switches around the other side of the ring.
How can you disable the drip sensor in a enteral feeding pump?
== == What an interesting question. Since this isn't an 'on' or 'off' situation, I would have to ask the manufacturer, although they may be reluctant to tell you how. I might try to play it up like you are a tech, and are having problems with the sensor. Tell them you need to 'temporarily' disable it and see where it leads you. Good luck, I'd be interested to know how it works out, but I'm afraid its probably built into the chip that controls the unit.
I hope this doesn't end up as a 'Law & Order' episode
How many dB attenuation translates into 75 percent of voltage being lost to attenuation?
100 percent means full voltage or 0 dB.
When 75 percent of the voltage is lost you still have 25 percent of the voltage.
25 percent means damped to (-)12 dB.
What is the input voltage at which a diode will pass current?
As close to virtually zero volts as is possible: the current will very small but there will be current.
This depends on two things: the material that is used to make the diode, and whether the voltage is applied in a forward or reverse direction to the diode. A typical silicon diode will pass forward current above 0.6 V and pass no reverse current until a much higher voltage is applied (check the rated peak inverse voltage PIV)
First of all the power consumed is only dependent on the load (eg. any appliance) connected to the source. A load will always draw its rated power. If you have increased your voltage to twice then the current drawn by the device will become half but the power consumed will remain same.
the power consumed is given by:
P= V*I* cos(fi)
here for a given load P(power), cos(fi) are constants.
Then if V becomes 2V then current will be I/2.
What would be the best medium for an environment that is subject to heavy emi?
Fiber is best.
Cat6 would be next best, but is not as good as fiber.
How does a television transmitter work?
A television transmitter works by converting audio and video signals into radio waves for broadcast. It first encodes the video and audio information into a modulated signal, typically using techniques like amplitude modulation (AM) or frequency modulation (FM). This modulated signal is then amplified and transmitted through an antenna, which radiates the waves over a specific coverage area. Receivers, such as televisions, capture these waves and decode the signals back into audio and video for viewing.
What are optical fibers made of?
Good optical fiber is made of glass, but inexpensive fiber is sometimes made of plastic.
(a) what is the total capacitance of this arrangement (B) the charge stored on each capacitor (C) the voltage across the 50 micro farad capacitor and the energy stored in it. 20v and 20+30+50 micro farad
The relationship between resistance and conductors is?
ALL resistance are conductors. just the magnitude value changes
When a larger voltage is applied to a conductor does the current increase or decrease?
If you increase the voltage applied to a conductor, the current increases.
That is, unless you are talking about stepping up the voltage with a transformer with the intent of distributing it over a long distance to a remote transformer, at which point you would step it back down. In this case, the current would decrease. The above answer to the original question remains valid, however, due to lack of information.
How much current was in the circuit?
I'm sure I can answer this if given more details, what circuit? current is determined by voltage and impedence(resistance) in a purely resistive circuit it is pretty basic, in alternating voltage circuits the impedence is dependent on the frequency of the voltage/current. inductors and capacitors are designed into a/c circuits to force the load to behave like a resistive circuit which boils down to how much voltage divided by how much resistance you have, 120 volts divided by 10 ohms equals 12 amps. in a parallel circuit it works pretty much the same way voltage placed on the resistor divided by its resistance equals the current flowing through that leg. more details please.
