Term used to describe how much heat a circuit dissipates?
Power dissipation.
Where does the heat from a furnace keeping your house warm go?
The heat pretty much stays in your house. The heat from the furnace rises (because the molecules have moved apart) and goes to the top of the house. There it cools down, and because it is not more dense, it sinks back down to the furnace where it can be made warm again. All this happens through a process of heat transfer call convection.
Which bulb will glow brighter with 220V - 40W or 400W?
-- The voltage makes no difference. -- The 400W device dissipates ten times as much power as the 40W device does. We don't know how much of each one's power consumption is radiated in the form of heat, UV light, etc. But if the spectral distribution of their output is similar, then the one that dissipates more power produces more visible light, and appears brighter.
Why does rug in a room warmer than tile in the same room?
It's not a case of the rug being warmer. It's that the tile is very dense, and that conducts away the heat of your feet rapidly - "the floor is cold". The rug traps a lot of air in it's fiber, and the air insulates your foot from the floor.
What is the name of the field of study with laws that describe how much energy is transferred to different locations and forms?
Thermodynamics is the field of study that deals with the laws governing the transfer of energy between different locations and forms. These laws describe the relationships between energy, work, heat, and the properties of systems.
Term used to describe how much heat a circuit dissipates?
Power dissipation.
How much heat a human dissipates in 1 hour while sitting idle?
This depends upon external temperature, humidity of the air and air flow out side the body. Human can perspire up to one liter of sweat. So he can dissipates the the heat required to evaporate that much water.
How much amount of heat will produce in 22kilo ohm resistor?
If the resistor is conducting electrical current, then the power it dissipates (heat energy per second) is(current through it)2 times (22,000)or(voltage across it)2 divided by (22,000).If the resistor is connected in an unpowered circuit, or stored in a drawer, then it dissipates zero heat.
What object keep too much Current from flowing through a circut?
fuse
Why is the temperature on the surface of Jupiter much lower than that on earth?
The "Surface" of Jupiter is hard to define as it is a gas giant but the top of the atmosphere (however you want ti define that) is cold due to heat radiating into space. Jupiter is so much farther from the Sun than Earth is, the Sun cannot heat Jupiter's atmosphere. And the heat form the interior (it is actually hotter than the surface of the Sun deep inside Jupiter!) dissipates into space.
What property of a substance does its specific heat capacity describe?
How much heat it takes to raise the temperature
What would happen if a wire is too narrow and the current is too strong?
Too narrow for what ? Too strong for what ? A narrower wire has higher resistance. The power (heat) dissipated by the wire is . . . (current)2 x (resistance). -- If the resistance is low and the current is low, the wire dissipates very little heat. You don't notice it, it doesn't start a fire, and the circuit that the wire is part of works fine. -- If the resistance or the current is somewhat higher, the wire dissipates more heat, and it gets warm. -- If the (current2 x resistance) is still higher, then the wire dissipates a lot of heat. It can be used in a toaster, a hair-dryer, an electric coffee percolator, or an electric baseboard heater. -- If the wire is inside a container from which the air has been removed, and the (current2 x resistance) is high enough to cause a short section of the wire to dissipate a fair amount of power, then you've got yourself a light-bulb. -- If the (current2 x resistance) is high enough to cause the wire to generate so much heat that it melts, then you have a fuse, which just blew.
What are ways to adapt to global warming?
Somewhat, if the ozone layer dissipates too much there will be too many UV rays for us to handle. For now, we can handle it even though it might be difficult for the people who like winter! We can take it for a long time, we can handle the heat but the Sun on us with no protection will someday be too much.
What does voltage mean in a sentence?
Voltage pretty much means.. The work it takes to move charge from one point of the circut to anotherl.
What term describes how much energy it takes to change the the temperature of a substance?
specific heat capacity
Where does the heat from a furnace keeping your house warm go?

Why is a resistor heated by a ac current?
A resistor is heated by any power source, AC or DC. Voltage is joules per coulomb. Current is coulombs per second. Voltage times current is work in watts or joules per second. This is heat transfer, and is manifest by the resistor getting warm. Actually, any device that dissipates power will get warm. Some of the heat energy is consumed in doing other work, such as in producing light in a light bulb, but much of it also produces heat, also such as in producing heat in a light bulb.
