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.

Does the bulb light up in a parallel circuit?
The bulb will shine as long as it is still part of a complete circuit. You probably have a diagram for such a circuit. See if you can still trace a path through the battery and one of the bulbs without passing through the other bulb. For comparison, try the same thing with a diagram of a series circuit.
ac is used as it can travel farther in most conditions losing less energy making it more
efficient to travel to different houses, although most high power appliances like computers convert dc because it is more condensed energy
What type of diode produces light when properly biased?
That would be an LED or Light Emitting Diode an LED is a light
How much does a pair of flip flops weigh?
depends where you want to buy your flip flops
they can range anyware form $1 to $50
What is the most common element of a semiconductor?
One element that is semiconducter is Silicon.
2nd answer:
One common element used to manufacture a semiconductor is silicon. Germanium has also been widely used, and is more sensitive to tiny voltage changes than silicon. The compound gallium arsenide is very common in the manufacture of semiconductor material, as well.
BJT is Bipolar junction transistor FET is Field effect Transistor
It is a current controlled device It is voltage controlled device
Why does the current in an electric circuit decrease when more bulbs are added?
If you add one extra bulb and the voltage remains constant, then you have doubled the current drained from the regulator.
12 Volt and One 12 Watt light bulb drains 1 Ampere Current.
12 Volt and Two 12 Watt light bulbs drains 2 Ampere Current.
However:
If having a 24 volt power source and you add two 12 Volt 12 Watt in serial, then you still only drain 1 Ampere Current.
NOTE:
Wattage and Voltage of bulbs may be different even if the sockets are the same.
Lower voltage on the bulb will increase the current drain, if voltage is a lot lower it might cause the circuit delivering voltage to burn out or blow a fuse. It can also quickly burn the bulb, sometimes in a fraction of a second.
It will however do little damage to add a bulb with higher voltage than the circuit is designed for. You will then only observe that you do not get the light you might hope for.
Total Current/Ampere= Combined Wattage divided by Voltage
Total Wattage = Combined Current or Ampere multiplied by Voltage.
In simpler words:
If you double the bulbs, twice the current is drained from the battery
What is the function of a rectifier within an alternator?
A rectifier turns the Alternating Current (AC) produced by the Alternator into Direct Current (DC) that your car uses.
What is the frequencies in the range of RF waves used by commercial radio broadcasting stations?
Each country has different frequency bands allocated for AM and FM radio. In the U.S. AM takes up the range from 535KHz to 1605KHz. FM radio takes 88.0MHz to 108.0MHz.
Each radio station then receives a slice of that frequency band, regulated by the FCC. Each station is typically given a frequency far from all other stations. For example, three stations would be given the frequencies 93.3MHz, 94.5MHz and 96.1MHz. In theory, the stations could be closer (ie 94.3MHz, 94.5MHz and 94.7MHz) though this is rarely done because each station would then cause more interference to its neighbors.
(The stations don't actually 'cause interference' to their neighbors. The weakness
is the ability of consumer-grade receivers to separate stations whose frequencies
are close together.)
What happens in a series circuit if the resistance is halved?
If you add a second resistor, the resistance of series circuit will increase.
How much power consumed for laser diode?
The power consumption of a laser diode typically ranges from a few milliwatts (mW) to several watts, depending on its type and application. For example, low-power laser diodes used in optical devices may consume around 5-100 mW, while high-power laser diodes used in industrial applications can consume several watts. The specific power requirements also depend on factors such as operating conditions, output wavelength, and intended use. Always refer to the manufacturer's specifications for precise power consumption details.
Can anythang besides metal conduct electricity?
All wires conduct electricity, since wire is always made of metal, and all metals are conductors.
Copper is preferred though, as it has the highest electrical conductivity rating of all non-precious metals. It is also very ductile when annealed, so can be drawn into wire of anything down to sub-millimetre diameters.
Other metals are used for other properties. Aluminum wire has a higher conductivity to weight ratio and lower cost, for instance.
What is the function of 240 ohms resistor?
To provide 240 ohms of resistance.
What those 240 ohms do in an actual circuit depends on the intention of the designer.
Why the bridge rectifier is best?
What is the advantage of using the bridge rectifier
A: NONE no advantage the only advantage can be considered it the fact it will provide more voltage but never more power actually less by a .7 volt diode drop
Material sent out of the factory and should return the same within 6 months time.
Why do you connect galvanometer in series?
You connect a galvanometer in series with the circuit being measured, because the galvanometer is a form of ammeter, although an extremely sensitive one, and ammeters measure the current in a series circuit.
Because that is what a capacitor used to be called - a condenser.
Answer
Used in this context, the word 'condenser' is derived from the Latin for 'to make smaller'. Early capacitors, such as the Leyden Jar, were able to store separated electric charge in a much smaller volume than methods hitherto used. So early capacitors were called 'condensers'. In France and Germany the older term remains in use.
Which type of current invovles flow of charge in two directions?
A direct current involves change of flow in a single direction. DC (direct current), at least on the macro scale. On the atomic scale, they seem to wander all over the place between atoms, and the average movement is what we measure as current.
How does a transistor amplify in a common emitter configuration?
The base is excited by a very low current. That turns the transistor on so that a higher amount of current flow comes out.
There is not any fullform of verilog.Infact the whole word is called "Verilog HDL" which is "Verilog Hardware Description Language".
In frequency modulation what happens to the bandwidth when you increase the modulating frequency?
Bandwidth increases as a function of both modulating frequencyand deviation. As deviation increases, pairs of sidebands are generated, each equal to fc+m and fc-m, fc+2m, fc-2m etc. where fc = the carrier frequency and m = the modulating frequency. Increasing modulation (frequency deviation) will change the level of each of the sideband pairs - and the carrier, which at times falls to zero.
What is the effect of diode voltage drop as the output voltage?
The effect of diode voltage drop as the output voltage is that the input voltage will not be totally transferred to the output because power loss in the diode .
The output voltage will then be given by:
vout=(vin)-(the diode voltage drop).
A: 7400 has a propagation of 10 ns and the power dissipation is m10 from DC to 35 mhz maximum input hi level 40 ua maximum low level input current is -1.6 ma and there is more but you can find the date from manufacture data sheet specification for this device basically that what a specification does and is.
How inductance is produced when electric current passes through a conductor?
Electric charges interact with changing magnetic fields. All magnetic field changes can be thought of as the magnetic field moving. If the magnetic field strength is increasing then it is the same as a magnet being brought nearer while a decreasing magnetic field is the same as if a magnet is being pulled away.
The force a charge experiences is the result of several factors. The direction of the force depends on the polarity of the charge, whether it is positive or negative, the direction of the magnetic field and the direction of relative motion between the charge and magnetic field. The magnitude of the force, its strength, depends upon the amount of charge, the strength of the magnetic field and the speed of the relative motion between them.
So you can make charges inside a piece of wire move by waving a magnet near the wire. If the wire makes a circuit, then you get electric current flowing through that circuit. A generator is a device which uses the interaction between charges and changing magnetic fields to create electric current. Generators require a source of mechanical energy to run. Portable generators typically use gasoline while generators used by the electric power company can be driven by water, wind, coal, natural gas or the heat from nuclear fission. Coal is the most common source of energy for electricity in the United States.
