What else can I help you with?
Only a small percentage of the electric energy going into a common light bulb is transformed into light what happens to the rest?
The rest is dissipated as heat.
Why do some regulators need a heatsink?
Most linear regulators absorb the amount of energy equal to (Vin-Vout)*I where Vin is the voltage into the regulator, Vout is the regulated output voltage, and I is the current flowing through the regulator. This energy is dissipated as heat. As to much heat will burn the device out, a heatsink is needed where the die of the device cannot adequately dissipate the waste heat into the atmosphere.
Who is the Indian atomic energy commission chairman?
the current(1.1.11) atomic energy commission chairman is Dr.S.banerjee.
Why 250 volts AC in New Zealand instead of 110 volts AC which America uses is one safer and is more energy footprint required to produce the higher voltage?
The reason for increasing the voltage in the electric network is, in fact, that it saves energy. The power dissipated in electric wiring is proportional to the square of the electric current. By increasing the voltage, the current decreases provided that the power consumption at the consumer is to remain constant. This means less loss in the electric network. For the same reason, very high voltages, hundreds of thousand volts, are used in long-distance wires. The voltage is converted using transformers when it reaches the consumers, with a relatively low power loss.
How much heat energy will a 40W light bulb give out in 3 minutes?
Joules = watts x seconds. Just convert the minutes to seconds, then multiply.
How can I find the energy dissipated in the resistor?
To find the energy dissipated in a resistor, you can use the formula: Energy (current)2 x resistance x time. This formula calculates the energy dissipated in the resistor based on the current flowing through it, the resistance of the resistor, and the time the current flows.
What is dissipated energy?
Dissipated energy is the energy that is spread into the environment or lost
What is energy that is dissipated in a crash?
Kinetic Energy is energy that is dissipated in a crash.
What is the relationship between the resistance of a material and the amount of thermal energy that is released when electrons move through the conductor?
It isn't QUITE as simple as that. The relevant formula is: (power dissipated) = (current squared) x (resistance)So, the amount of energy dissipated not only depends on the resistance, but also on the current (that's what is measured in amperes). For example, if there is no current, there will be no power dissipated. The formula is about POWER; to get ENERGY, which is what you asked for, you need to multiply power by time.
If current in an electric stove is doubled how will the thermal energy produced per unit time change?
P = I2R (power = current squared times resistance). Therefore, if the current doubles, the amount of dissipated electrical energy will increase by a factor of 4.P = I2R (power = current squared times resistance). Therefore, if the current doubles, the amount of dissipated electrical energy will increase by a factor of 4.P = I2R (power = current squared times resistance). Therefore, if the current doubles, the amount of dissipated electrical energy will increase by a factor of 4.P = I2R (power = current squared times resistance). Therefore, if the current doubles, the amount of dissipated electrical energy will increase by a factor of 4.
Energy that is dissipated in a crash is called?
Kinetic Energy is energy that is dissipated in a crash.
Is Q factor ratio of energy stored to energy dissipated?
yes ,Q factor is ratio of energy stored to energy dissipated
If a current of 4.5 amps flows into a 3.5 ohm resistor for 5.5 minuits the energy dissipated is?
The power dissipated by a resistance ' R ' carrying a current ' I ' is [ I2R ].I2R = (4.5)2 x (3.5) watts = 70.875 joules per second5.5 minutes = (5.5 x 60) = 330 secondsEnergy = (power) x (time) = (70.875) x (330) = 23,388.75 joules
Is an exothermic reaction categorized as dissipated energy?
An exothermic reaction releases heat energy to the surroundings, so it is not considered dissipated energy. Instead, it is a form of energy transfer from the system to the surroundings. Dissipated energy refers to energy that is lost as heat and cannot be used to do work.
What are examples of dissipated energy?
One example of dissipated energy is when using a light bulb. This is when elctrical energy is converted to light and heat energy. However, the only useful energy here is light energy as light bulbs do not need heat to function. Therefore, when you touch a light bulb it is hot and this is the dissipated energy as it is wasted and not needed.The energy dissipated is heat. In any example of transferring energy there is always dissipated energy and other examples are when cars are used. The energy is converted to kinetic energy but is also converted to sound energy which, in this example, is the dissipated enrgy.
What is the energy lost formula used to calculate the amount of energy dissipated in a system?
The energy lost formula used to calculate the amount of energy dissipated in a system is: Energy Lost Initial Energy - Final Energy.
How is energy dissipated from a car engine?
Heat
