What do two devices need to have in common in order communicate successfully?
A signal
What is the auxiliary power outlet in a car used for?
I use my to charge my cell phone & for the GPS system. With the proliferation of hand held equipment, there is a greater need for the ability to plug in and use or charge these devices, especially with more than one person in the car each needing a power outlet.
Do you need a battery to make a circuit?
no, but you do need a power source, such as a cell or a power pack if you do not want to use a battery.
What are the advantages and disadvantages of atomic power station in koodankulam?
basic imporent need is power so power plant need. it may cause harmful diseases
What is better uninterruptible power supply or automatic voltage regulator?
It depends on the application, and on the implementation of the UPS. Some UPS devices function as an AVR by boosting the output voltage when the input voltage sags. A UPS will also help you during a complete power outage, which an AVR will not. A UPS however has batteries which need to be periodically replaced. An AVR does not, which means less maintenance.
Passive prosthetics came about to meet what need?
the need for devices to function without an external power source
How do you make a power supply?
It depends on what you want to use it for. Assuming you will be working with a 110 volt AC input and want a 9 or 12 volt DC power supply, you will need a transformer to reduce the AC voltage, then you will need a rectifier to convert it to pulsating DC (a full wave rectifier works better than a half wave rectifier) and a capacitor to smooth out the pulses. Some devices like solenoids and valve actiuators work well with pulsating DC but some applications demand pure DC. That is the basic design of most power supplies. You may need to regulate the voltage which is required in some applications.
Why is my lawn mower pulsating?
If your lawn mower is pulsating, it may mean that it is not getting enough fuel and the carburetor may need cleaning.
What need do passive prosthetics come to meet?
Passive prosthetics are designed to meet cosmetic needs by looking natural and resembling the missing limb. They do not have any functional capabilities and are typically used for aesthetic purposes or to improve body symmetry.
What is the source of power for a vehicle tracking system?
No, most tracking devices run on the battery and need it to function. Special tracking devices may have a separate power source such as internal battery.
What are power saves?
Power Saves are devices that lets you change your saves. You need an Internet connection to download, then backup the saves for your game.
What is need of Flexible AC transmission system devices?
Flexible AC transmission system means inserting power electronics based devices in series ,in shunt,in series and shunt to improve the power transfer capability
Cause of pulsating brakes?
Rotors may be out of "round" (lateral runout) and need to be resurfaced or replaced
Why some things need mains electricity and others need battery?
Portable devices that do not consume large amounts of power can be run on batteries. Some battery powered devices can also be powered by mains - running a 'battery eliminator' - to save from having to purchase batteries. Devices that consume large amounts of power are usually best powered by mains.
Do sockets need to be accessible if something is plugged in?
No, they do not. Switchboards must be accessible but the field devices do not, including power outlets.
What is the difference between TTL and CMOS interms of fan infan outlogic levelspropagation delay?
The power dissipation of CMOS devices is around 100 times lower than the value of power dissipation for TTL. This makes CMOS more suitable for devices to run on battery power and devices allows like mobile phones to have a longer batter life. CMOS devices only use power when switching from one state to the other state (high to low, or low to high) so on they need power for less of the time than TTL devices which use current and dissipate power all the time that they have a power supply.
Do you need to hook up a power cable if your using SATA drive?
Yes; power is not supplied by the data cable. An exception might be a small-form-factor, external, USB-connected drive, as the USB port can power low-power devices. If an external USB hub is expected to power external devices, it's best if the hub itself is powered, otherwise available power is split among too many devices, potentially leaving something underpowered.
