What else can I help you with?
What is the heat produced by a 10 ohms resistor with a current of 1 ampere in a minute?
Heat=i^2*R*t=10*60=600 joules
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.
Why an electric toaster is considered a resistor?
An electric toaster is considered a resistor because it is designed to limit the flow of electric current, converting electrical energy into heat. The heating elements in the toaster have high resistance, causing them to heat up and toast the bread placed inside.
How do you find power generated in a resistor?
The power generated in a resistor is converted into heat. and that can be power which is converted into heat is the product of the voltage across the resistor and, current passing through the resistor. or the product of square of the current and the resistance offered by the resistor.
What ic joules losses?
Joule's law states that the heat produced in a resistor is directly proportional to the square of the current passing through it and the resistance of the resistor, as given by the formula ( P = I^2R ), where P is power, I is current, and R is resistance. This heat is often referred to as "Joule heating" or "Joule losses".
Why does a resistor heat up when an electric current flows through it?
Current moving through a resistor causes it to heat up because of the flowing electrons bumping into the atoms in the resistor.
Why should care about resistor temperature increase?
You should care about resistor temperature increase because it can lead to changes in the resistor's electrical properties, such as resistance value and tolerance. Excessive heat can also reduce the lifespan of the resistor and potentially cause it to fail. Monitoring temperature is important to ensure the resistor operates within safe limits and provides accurate performance.
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...
How do you use resistor in a sentence?
I installed a resistor inline with my oil pressure sensor. The resistor in a circuit will usually disperse energy as heat.
Where is the resistor on the Chevrolet Impala?
If you are referring to the blower motor resistor then it is inside mounted on the evaporator case.
Resistor get hot when electrical charge flows through it?
When an electrical charge flows through a resistor, some of the electrical energy is converted into heat due to the resistance of the material. This heat causes the resistor to get hot, and the temperature increase is proportional to the amount of current flowing through it and the resistance of the resistor. If too much heat is generated, the resistor may be damaged or experience a change in resistance.
Does a resistor use electrical energy as it interferes with the flow of charge?
Yes, a resistor converts electrical energy into heat as it interferes with the flow of charge. This energy is dissipated in the form of heat due to the resistance of the resistor material.
