What is solar heating device?
The sun seems to be a pretty good heating device. Sure keeps the earth warm
What is the working of economizer in a boiler plant?
Economizer is a device in which the waste heat of the fuel gases is utilized for heating the feed water.
What type of device is used to collect solar energy for heating water and houses?
Solar panels and heaters are used. They trap sun's energy.
What will happen when a machine run at low voltage?
The results of operating machinery at a reduced voltage depends on the type of machinery and the power supplies used in the equipment. In many cases, the current drawn will increase to allow a device to operate at a constant power. In others cases such as heating, thermostats will switch on heating elements for longer periods of time to achieve a required temperature. In some simple machines, motors will deliver less power because of the reduced voltage. Although most equipment will operate at lower than rate voltages, there will be a voltage threshold below which it will not operate at all.
Is antenna passive or active component?
An active antenna is an antenna which has an amplifier attached very closely to it. The antenna/amplifier system is called an active antenna. It is used for receiving signals only. The idea is to set the signal-to-noise ratio (SNR) before the signal travels along a transmission line where it is susceptible to interference and loss.

What is temperature of heating element how to measure it if we know applied voltage or current. Is the temperature said to be even?
When talking of heating elements in the electrical trade the unit of watts is used. The higher the wattage value of the device the higher its temperature output. Heating cables are measured in watts per foot as a way of measuring their heat output. The equation to find wattage of a device is to multiply the voltage of the device times the amperage of the device as stated on the device's nameplate or tag. In most cases the temperature is linear throughout the length of the heating element. The actual temperature can be tested by using a laser spot temperature test instrument.
What are electric baseboard heaters classified as?
Heating device or heating element.
What material is used to make the heating coils of electrical heating device and why?
Nichrome
Where does a hair straightener catch fire?
The hair straightener catches fire beside the heating elements. The device itself does not catch fire until after it has caught nearby combustibles on fire. The heating element brings nearby combustibles up to their ignition temperatures.
How do you activate your 32 GB micro sdhc memory card?
The first time you insert it into a device - the device will initialize it.
Which device can be used for both cooling and heating?
Vaporizer
How do you activate your bluetooth on your cell phone?
Get the manual out for your Bluetooth device and follow the instructions there. Usually you will have to go to the Bluetooth option in your phone menu, scan for the Bluetooth device, and enter in the code that is written in your manual. After that you should be connected. Each Bluetooth device is different however, and that's why you need to read the manual to figure out exactly how to activate your device.
