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.

What is the function of monitoring voltage relay?
A voltage monitor relay is in the circuit for one reason. It monitors the incoming voltage to the equipment that it is protecting usually on three phase control panels.
The relay monitors the three incoming line voltages and in some relays the voltage to ground (wye connection). If the circuit the relay is protecting looses one of the voltage legs, the circuit will shut down until the problem is rectified. This usually happens if a fuse blows in one of the three phase voltage legs.
It also monitors the level of voltage to the circuit. If the voltage drops due to a malfunction in the utility lines the relay will trip and take the protected circuit off line. The voltages can be set to trip at any under or over voltage usually by set point controls on the front of the voltage monitoring relay.
What is it meant by adaptive problem of control system?

How is faradic stimulation different from electoconvulsive shock?
Faradic stimulation is a small battery-operated "shock stick" with less electrical current and then a pace maker is used. The patient is put to sleep and given a muscular relaxant. A small amount of electric current is then applied to the patient's temples. This produces a seizure.
where as- Electroconvulsive shock(ECT) is induced by attaching two electrodes to each side of the head and passing an electric current through them producing convulsions in the patient. Following this, a state of coma occurs lasting from several minutes to several hours. It is not certain which particular aspect of the shock process bring about positive changed--the coma,the changes in the nervous system from the shock, the violent psychological reaction, or the idea that the patient has taken the shock as punishment which reduces their sense of guilt.
also.- Somatotherapy refers to the treatment of the body for behavioral disorders with such methods as shock treatments, surgery, or drugs. Shock treatment has received mixed reactions. The use of insulin shock was very popular. An overdose of insulin was administered causing a patient to become unconscious.
When the brain lacks sugar through the process of shock, normal pathways to the brain are reintroduced and fortified. Therefore insulin shock returns the patient to normal functioning.
hope this helps:)
by the way im not a professional or anything.
How do you stop flip flop from flopping?
tape it to the bottom of your foot! (
answer is not in detail) naah...just take them off.
Current = Charge / Time
= 90 / 0.02
= 4500 Amperes
The term Hertz (abbreviated Hz.) is used to describe the frequency with which current changes its' direction of flow in a second. Such as, our system frequency is 60 Hz.
When you double your distance from a speaker you lose how many db?
Sound pressure is inverse square law for distance, so doubling distance from a speaker cuts the power by 4. Since the db scale is 3 times log2 (power ratio), a reduction of power by 4 represents -6db.
What circuit would be inside a torch?
you have to collect a battery(cell), battery case, 4 wires, and as many bulbs as you ewould like. now link them together. alexia age 12
A very good answer Alexia.
Here's how I would answer it.
Connect, in series, a cell or battery, a bulb with a voltage rating which corresponds to the cell/battery voltage, and, optionally, a switch.
What is advantages of multimeter?
This handheld mini digital multimeter features easy-to-read LCD readout, low battery indication, fuse and diode protected circuit. Easily fits in a shirt pocket, yet despite its size it is a rugged, full function multimeter that performs the following...
"Motor control" generally refers to the physical dexterity of a human or other animal.
It is primarily affected by two things:
Physical condition: general bone/muscle structure
Mental condition: ability of the brain to interact with the muscle system. Typically divided into rapid motor control (ability to create rapid gestures that cause significant motion) and fine motor control (the maximum level of precision that can be achieved)
What are the problems one can expect with low supply voltage or fluctuations in split AC?
depends on how low incoming ppower is unit will have min max allowable voltage on name plate but the lower the voltage the higher the amperage draw which can reduce life of compressor or even kill it
Where can you buy a personal Doppler radar unit?
EWR Weather Radar Systems manufactures a small portable unit (E600) Portable, not sure about... personal
It was to take care of Selena and also she was a striper.
Is a high pass filter and a low pass filter the same thing?
Yes, they are both filters.
But their frequency characteristics are different. This is the main reason why they are given different names.
A high-pass filter passes frequencies higher than its cut-off frequency, and stops those that are lower.
A low-pass filter passes frequencies lower than its cut-off frequency, and stops those that are higher.
Do you need to apply a load to see a voltage drop across a resistor?
You'll see a voltage drop across a resistor if current is flowing through it. It only
has to be a part of a complete circuit, i.e. one in which current is flowing.
Zinc oxide (ZnO) is typically considered an n-type semiconductor due to the presence of intrinsic point defects, particularly zinc vacancies (VZn) and interstitial zinc atoms (Zni). These defects create extra electrons in the conduction band, enhancing its electrical conductivity. Additionally, when doped with elements like aluminum or gallium, which have more valence electrons than zinc, ZnO can further increase its n-type behavior by providing additional free electrons. Thus, the dominant charge carriers in ZnO are electrons, confirming its n-type character.
