What electrons moving through a resistor transfer some of their energy to the resistor in the form of?
When electrons move through a resistor, they encounter resistance, which causes them to collide with the atoms in the resistor material. These collisions result in the transfer of kinetic energy from the electrons to the atoms, increasing the vibrational energy of the atoms. This energy transfer manifests as thermal energy or heat, leading to an increase in the temperature of the resistor. Thus, the energy lost by the electrons is converted into heat energy due to resistive heating, also known as Joule heating.
What else can I help you with?
Is voltage established through a resistor or across a resistor?
Current = charge (electrons) flowing through a resistor.Voltage = energy lost across a resistor.Power = energy lost across a resistor per second.So yes you are correct. Current is established through a component, while voltage and power are established across a component.Answer'Voltage' is a synonym for 'potential difference'. As the name implies, voltage describes the difference in potential between (or 'across') two different points. So voltage is applied ACROSS a resistor.Further to the original answer. voltage is NOT equivalent to 'the energy lost across a resistor', and power is NOT 'established across a resistor' (power is simply a 'rate', nothing more)!
Why schottky is called hot carrier diode?
Because the energy of electrons transfer from semiconductor to metal side have more energy than the fermi energy of electrons in metal side. That's why these are called hot carrier diodes
What effect does energy have on a resistor?
One way to look at the purpose of a resistor is as a device built to dissipateelectrical energy. Some (but usually not all) of the energy of the current througha circuit is always dissipated when it flows through a resistor. The energy lostleaves the resistor in the form of heat.The number of joules of electrical energy lost and heat dissipated by the resistor is(amperes of current through the resistor)2 x (ohms of resistance) x (seconds of time it continues)If you work with resistors often, or see several of them inside an old radio, you noticethat there are physically big ones and physically small ones. The size of the resistorisn't related to the number of ohms of resistance it has. The physical size is relatedto how fast it can dissipate energy (heat) without melting or burning up. A biggerresistor has more air around it, so it can get rid of heat faster.
How to calculate the heat produced in a resistor?
Resistors dissipate heat energy with power P=I2R. Since power is defined as energy gained or lost per unit time, we can solve for the energy lost using E=Pt, where E is energy (joules), P is power, and t is time (seconds).Finally, substituting the definition of power into the equation you get:E=I2RtAnswerWith difficulty. The original answer, unfortunately, tells us the work done on the resistor and not the heat transfer from the resistor, which is what the questioner is asking.The work done on the resistor is the product of the square of the current and the value of its resistance. This will increase the internal energy of the resistor and increase its temperature above that of its surroundings, and heat, by definition, is the energy transferred from the higher temperature resistor to its cooler surroundings.So there are simply too many unknown variables to take into account: the mass of the resistor, the specific heat capacity of the material from which it's made, the temperature difference between the resistor and its surroundings...
Electrical resistance is caused by what?
Resistors and semi-conductors. As electrons travel through these less conductive substances they collide with more atoms, typically converting some of their energy to heat and light. Consider a common light bulb - the tungsten filament is a simple resistor - the tungsten atoms partially block the electrons traveling through, converting their energy to light and some heat.
What energy transfer takes place when the current passes through a resistor?
When current passes through a resistor, electrical energy is converted into heat energy, which causes the resistor to heat up. This process is known as Joule heating.
Do electrons lose energy or speed when they cross over a resistor?
Electrons lose energy when they pass through a resistor due to collisions with the atoms in the resistor material. This loss of energy manifests as heat. The speed of electrons may decrease as a result of this energy loss.
What type of energy transfer occurs between electrons?
Electrons transfer energy in the form of electrical energy. When electrons move through a conductor, they create an electric current that can carry energy from one point to another.
What causes a resistor to heat up?
The current through a resistor or for that matter any conducting medium is caused by flow of electrons. These electrons do not flow like a stream through the resistor or conductor but undergo repeated collisions with the vibrating atoms of the resistor, transferring their kinetic energy to them. This in turn increases the vibrational energy of the atoms and manifest itself as heat in the resistor/ conductor. In turn this results in reduced drift velocity of the electrons resulting in reducing the current , thus acting as a Resistor.
What does it mean when you say that energy is lost in a resistor?
When we say that energy is lost in a resistor, it really means that electrical energy has bee transformed into other forms of energy. These other forms of energy do not easily get changed back into electrical energy.
How do electrons help in transfer of heat energy?
when a substance is heated,the molecules in that substance get heat energy. we know that all of the molecule in the substance having electrons. when substance is heated. electrons becoming high energetic.and they move faster and also energy will propagate though out the substance
Why is heat generated across a resister when electric field is applied?
An electric current contains energy; so does an electric field. When a current flows through a resistor, part of the electrical energy will be wasted - i.e., converted to heat. You can think of this as if some of the electrons crash into atoms, instead of continuing on their way.
How is an alpha particle likely to transfer its energy?
An alpha particle is most likely to transfer its energy through ionization and excitation of atoms in the medium it passes through. This process involves the removal of electrons from atoms and the promotion of electrons to higher energy levels, resulting in the production of free radicals and secondary particles.
What is the process of heat transfer through a metal?
Heat transfer through a metal occurs through conduction, where thermal energy is transferred through the vibrating atoms or electrons in the metal lattice. When one part of the metal is heated, the energy is passed along the metal through collisions between neighboring atoms or electrons, causing them to vibrate and transfer the heat energy. Heat travels from the hot end to the cooler end until thermal equilibrium is reached.
Can you transfer energy through bluetooth?
No. You can not transfer energy through bluetooth.
What is it called when free electrons in metals transferring energy by colliding with other atoms or electrons?
It is called thermal conduction, where free electrons in metals transfer energy through collisions with other atoms or electrons, facilitating the flow of heat throughout the material. This process is a key mechanism for heat transfer in metals.
How can energy be transferred by means of electrons?
Energy can be transferred by means of electrons through processes like electrical current flow in a circuit. When electrons move through a conductor, they carry energy from one point to another, allowing electrical devices to operate. This energy transfer can result in the production of light, heat, sound, or other forms of energy.
