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.

Why should you be the internal resistance of the very few Amitr?
ammeter connect in series in circuit to measure the current, if the Ammeter have a high resistance it would effect the voltage value because there will be a drop voltage over the internal resistance of the Ammeter, so we desgin the ammeters with very low resistance...
That's a difference in electrical potential, not potential energy.
It's described in units of "volts".
What are integrated processes?
Integrated processes are as follow:
- Interpreting data
- Controlling variables
- Operational definitions
- Hypothesizing
- Experimenting
: , kindly look for their meanings if your interested: {^.*}
An autotransformer is a transformer where the primary and secondary are a single winding.
Why has your auto washer electric motor stopped working?
1 The pump is clogged and the motor can't start up. Most new energy efficient dishwashers are now fitted with very small motors with no get up go. 2 kill the breaker and pull an inspection. try to turn the motor - OK. Ok - Not more than a dozen other causes to look at now. Get the model number ready and search for "Appliance repairs". There you will find some very helpful help.
What is 7815 voltage regulator?
A LM7815 voltage regulator is a component designed to maintain a constant voltage level, the LM78XX series of voltage regulators are designed for positive inputs and has the ability to drive the current within the circuit up to 1A. The component has three legs: Input leg which can hold up to 36VDC, a leg that leads straight to ground and an output leg with the regulated voltage. For maximum voltage regulation, adding a capacitor in parallel between the ground leg and the output leg will improve efficiency.
What is decade capacitance box?
same as decade resitance box but instead of reitances there wil be capacitances
What is the purpose of a discriminator in an FM broadcast receiver?
The discriminator, and the ratio detector, perform the same function in an f.m. receiver as the detector does in an a.m. receiver, i.e. it recovers the modulation.
Why doping is require in semiconductor?
doping is done to increase the no. of holes in a semi conductor or to increase the no. of electron in order to conduct high amount of electricity , further info u can easily get from any 12th std. book.
What does the flashing of the leds on a PLC controller mean?
The item for which the LED indicates is in a fault condition. Since there exist many brands of PLCs, there are many conditions indicated such as BUS FAULT, SYSTEM FAULT, I/O FAULT, COMMUNICATION FAULT, and many others.
What is the advantage of bit-addressability for 8051 ports?
a powerful feature of 8051 I/O ports is their capability to access individual bits of the port without altering the rest of the bits in that port. of the four 8051 ports we can access either the entire 8 bits or any single bit without altering the rest
How we measures strain using microcontroller?
Measuring strain using micro-controller is simple and easy. When measuring using micro-controller you use points and condensers.
Why do we need a complete circuit for the bulb to light?
Its a power source such as a battery - Wire from the Positive on the battery to one contact on the lamp and a wire from the Negative of the battery to the other contact on the bulb
It is something that is not dependent on or relative to anything else. eg:- absolute zero.
one scientific meaning is "the apex" laymen terms mean for sure-- non better--- with out a doubt.
Why there is no current when two terminals of the diode are shorted?
There must be a break in the power supply elsewhere in the circuit. I suggest a blown fuse The only diode that generates electricity is a solar cell
A: TO measure the current on any path you will need a very small known resistance in sires and measure the voltage drop across it. If the resistance i not small then inaccuracy of reading will be evident
How single sideband is being generated?
In regards to the radio transmission mode, SSB is an improvement of AM, and there are generally three ways single sideband can be generated -- filtering out the unwanted sideband and suppressing the carrier; using phasing to suppress the unwanted sideband and carrier (Hartley modulator); or quadrature mixing and filtering (Weaver modulator).
Difference between smart and hart transmitter?
They are the same thing. A smart transmitter can be Hart, Fieldbus and in the case of Foxboro instruments FoxCom.
