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.

Sum or difference - so 28.5 or 18.5 KHZ All three frequencies still exist, not just the sum or difference.
Is an AudioBahn A800t a good amplifier?
yes it is you need to have good tune it and it pump out sound clean
An oscillator requires a phase shift filter and an amplifier. There are several different designs, based on the requirements, such as sinusoidal or pulse train output. Please restate the question and provide more information as to the type of oscillator required.
What voltage is needed to produce a current of 2 amps through a resistance of 6 ohms?
Where: V = Voltage (Volts), A = Current (Amps) and R = Resistance, (Ohms)
Here are a few easy and related equations.
V = A * R
R= V / A
A = V / R
So we have R=3 and A =6 and using the V=A*R equation we get
Volts = A(6)*R(3) = 18 Volts.
How do wind turbines fix global warming?
They generate electrical energy without also generating carbon dioxide, like other power plants.
The amount of energy they generate is very small compared to other power plants, though, so they do not have much effect.
Do wind turbines affect radio and television signals?
If placed in the wrong location, wind turbines can affect radio and television signals.
What can you use if you don't have a ESD wrist strap?
You can use a piece of ordinary wire or just leave one hand always touching the metalic ground of the device you're about to insert or remove circuits into or from.
What unit is power measured in?
The SI unit for power is the watt, which is equal to joules/second.
The SI unit for power is the watt, which is equal to joules/second.

Can a zener diode act as a surge protector?
Yes, and it's quite common to see one used as such. Whenever the voltage exceeds the rating of the diode, the diode will conduct and usually short circuit the excess voltage to ground. It's been commonly called a `crowbar circuit' and using the diode, it can be configured in several different configurations, depending on your application.
A zener designed for such applications is often called a TVSS or avalanche diode. These feature lower incremental resistance, faster response times, lower leakage currents, and smaller capacitance as compared to conventional zener diodes.
Downside of a zener diode is its tiny power handling abilities. Similar function is also performed using a Silicon Controlled Rectifier (SCR) for DC or a thyristor (triac) for AC.
Why does an electric circuit have to be closed for it to work?
yes it does have to be a closed circuit
im not sure but i think you meant to type idk which means "I Dont Know"
Can you use the vivitar zoom thyristor 2500 with Sony a700?
You can use it as an ordinary automatic flash, but the dedicated features such as TTL metering and auto-zoom will not work unless you have a flash specifically built for the Sony.
A potentiometer can act as a voltage divider?
Yes. One leg is connected to ground, the other leg is connected to the input, and the tap is the output.
it is a switching device that need a current..so u will need a resistor to open the switch..
What does asynchronously mean?
It is usually used with computer processes and it means independently.
What is interference between ic ttl and cmos?
Solution: Characteristics of CMOS logic: 1. Dissipates low power: The power dissipation is dependent on the power supply voltage, frequency, output load, and input rise time. At 1 MHz and 50 pF load, the power dissipation is typically 10 nW per gate. 2. Short propagation delays: Depending on the power supply, the propagation delays are usually around 25 nS to 50 nS. 3. Rise and fall times are controlled: The rise and falls are usually ramps instead of step functions, and they are 20 - 40% longer than the propagation delays. 4. Noise immunity approaches 50% or 45% of the full logic swing. 5. Logic levels in a CMOS system will be essentially equal to the power supplies since the input impedance is so high.
Characteristics of TTL logic: 1. Power dissipation is usually 10 mW per gate. 2. Propagation delays are 10 nS when driving a 15 pF/400 ohm load. 3. Logic levels vary from 0 to 5 volts

What is the Difference between active filters and passive filters?
Active transducers are those which require electric current (a source of energy) for working, while passive transducers are those which does not need an external source. Passive transducers directly produce electric signals without an external energy source.
An analog and digital integrated circuit.
Wrong, a hybrid IC is a device composed of individual separate components mounted on a tiny ceramic printed circuit board and encapsulated in a metal case or plastic resin. This is in contrast to a monolithic IC that contains everything on a single semiconductor chip.
An IC having both analog and digital functions is called a mixed signal IC.
What is the difference between analog and digital modulation Does it depends on baseband signal?
The basic difference is that in analog modulation the modulating signal is analog signal and in digital modulation it is in digital form.
How many ohms can a resistor have?
An almost unlimited number. Several million or several tens of millions of ohms are possible. At some point there is so much resistance that the resistor is almost considered to be an "open" or "open circuit" of the like. Bleeder resistors for bleeding off extremely high voltages or for use in voltage dividers used in high voltage applications can have extreme resistance values.
What is the maximum insulation resistance reading on a ring main circuit?
Insulation resistance is measuring the integrity of a conductor's insulation, therefore there is no upper limit as such. Most insulation resistance testers will indicate either >200 (Megohms) or >999 (Megohms) if they reach their maximum measuring capability. What you should be concerned with is the MINIMUM reading permissible: the current edition of BS7671 (17th Edition IEE Wiring Regs) specifies a minimum value of 1 Megohm (1 million ohms) as 'acceptable', but anything lower than 2 Megohms will require further investigation. Some electrical contractors would investigate much higher readings, especially if comparing readings with other circuits that have been tested at the same time, and which have given very high readings.
