Is it better to leave an electronic device on or to turn it on and off?

It depends on the device, power consumption and physical environment.
Computer equipment: Generally happier when left powered on with the exception of the hard drive and monitor (both of which have sleep modes available). The hard drive has moving parts that will eventually wear out if left running for prolonged periods. The solid state components have delicate soldering points that are prone to cracking if heated and cooled repeatedly.
Televisions: Tube televisions are best left off when not being watched. It saves power and causes less wear to the phosphorous coating in the tube. LCD TV's are best put to standby mode. Plasma screen TV's are MUCH better off when turned off -- the plasma screens have about a 7-year lifespan under normal conditions, and are very expensive.
Misc: Older electronics using vacuum tubes are way better off left on for less wear on the components, but will suck a lot of power. Anything with moving parts is best turned off such as DVD players, XBox consoles, or anything that reads moving media.
Environment: Humidity is an electronic nightmare. Leaving the component running will help to fend off the ravages of moisture, but make sure to clean any exposed vents regularly with compressed air. Vibration is very bad for electronics in an on state. If you live near railroad tracks or on a ship, electronics will be better off if you turn them off while not using them. This is especially true for high-heat components such as amplifiers, televisions, and computers.

Another concern is that many audiophiles feel that audio equipment, especially an amplifier, does not sound its best until it has come to a stable, warm operating temperature. That can take an hour or more.

What is advantages and disadvantages of SCR?
Advantages: simple turn On Latcing device, turn ON gain is very hih, low cost,Hih voltage and high current device. Disadvantages: Low switching speed, most suited for line commutated applications betwee 50 and 60 Hz can not be turn off with gate controlled. From: N.G.PATEL(UPS)B.TECH.(ELECT)
What happens if there is too much voltage?
it truly depends on the device that is supplied and what you mean by " too much". Generally overvotage is bad and will shorten the components life, considering it was desined and built to work in a certain range. Severe over voltage will cause almost all electronic devices will burn though very quickly. A motor windings will burn out in short order or the insulation will punch through and cause a turn to turn short. Purely resistive load will over heat and fail very quickly
What are the advantages of a silicon-controlled rectifier?
SILICON CONTROLLED RECTIFIER APPLICATIONS i) Speed control for motors ii) Temperature control for electric hot plate iii) Dimmer switch for domestic lighting iv) Dimmer control for stage lighting.
Is there any automatic car turn signal system?
Like an automatic indicator? If that's what you mean, you already have one in your car. The indicator will turn off when you have finished turning. It shouldn't take much to change it so it activates when you start turning. However such a device would not be practical (or safe) for use on the roads, as it would not give enough prior warning to other drivers.
Is SCR is a switch?
I's a electronic component that act like a controlled diode. It can be used as a switch on some applications, but with some limits. 1- A SCR is a diode, and as such, it only conduct in one direction. 2-The SCR only turn off when the current passing it reaches zero.
How do you turn the volume off on robot unicorn attack?
You can't. All you can do is turn off the volume on your electronic device.
Can you take your electronic solitaire game on an airplane?
Yes, however it is considered an electronic device and you will be required to turn it off during take off and landing sequences. Yes.
Does it cost more money to turn off a tv when left a room and then back turn it back on in a few minutes or does it cost less money to just leave it on when left a room for a bit?
There are two factors to consider:1. How much money will be saved by the savings in electricity when the TV is off?2. Is the life of the TV reduced by turning it on and off frequently, so you will have to pay to repair or replace the TV sooner?It will usually cost less to turn the TV off if you will be gone more than a short time.see "Is it better to leave an electronic device on or to turn it on and off?"
What is map digitalizing?
It is when you turn a map that you hold in your hands to one on a computer, cell phone, laptop, tablet, or other electronic device.
What is a technical chip?
A technical chip is an electronic device used to control certain operations. They may be things like chips to monitor temperature or to turn a device on based on a particular load.
Can you bring electronic toys in a plane?
You can take these type of games with you but since it is an electrical device they will probably make you turn it off during take off and landing.
How do you prevent the excess amount of current flows through the source?
An inrush current preventing circuit includes a rectification circuit, a temperature-sensitive component, a controller, a switching circuit, and a tank circuit. The controller outputs a control signal to turn on the switching circuit in response to the tank circuit being at a substantially full voltage, and the rectification circuit and the switching circuit forming a current loop for providing power from the rectification circuit to an electronic device. The controller outputs no control signal to turn off the switching circuit in response to the tank circuit being undercharged, and the rectification circuit and temperature-sensitive component forming a current loop for providing power from the rectification circuit to the electronic device for protecting the electronic device. the rectification circuit and the switching circuit forming a current loop to provide power from the rectification circuit to the electronic device;wherein the controller does not output a control signal to turn off the switching circuit in response to the tank circuit being undercharged, the rectification circuit and temperature-sensitive component forming a current loop to provide power from the rectification circuit to the electronic device such that an excess amount of current is prevented from flowing to the electronic device
Which of these is an expample of a time switch?
A time switch can be mechanical or electronic, and it is a device that can be set to turn off and on an electrical system at certain times every twenty-four hours.

How can you save energy at school?
Turn off the lights when you leave the class, and make sure the computers are turned off. Keep the taps, and anything else electronic, off when not in use.
Is it better to turn off an iPod Touch or leave it on?
It depends on the circumstances. If you know you are going to use it multiple times in the day, then you should just leave it on (but in sleep mode) and turn it off at night. If you plan to only use it every few days, then you should turn it off.
