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=I2Rt
Answer
With 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...
A convex lens cannot produce heat. It can focus incident heat to a smaller area so that it is more intense.
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.
A resistor by itself has no time constant. For a circuit to have a time constant it must contain either capacitors or inductors.
You need to calculate the equivalent resistance. For instance, if the three resistors are connected in series, simply add all the resistance values up. Then, you calculate the current (in amperes) using Ohm's Law (V=IR); that is, you need to divide the voltage by the resistance.
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.
heat is produce when you rubbed two things together...ex. stones
The heat generation formula used to calculate the amount of heat produced in a system is Q mcT, where Q represents the amount of heat produced, m is the mass of the substance, c is the specific heat capacity of the substance, and T is the change in temperature.
Heat=i^2*R*t=10*60=600 joules
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.
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.
yes you can! you can use a multimeter and a resistor.
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".
Current moving through a resistor causes it to heat up because of the flowing electrons bumping into the atoms in the resistor.
how calcualte conductivity
I installed a resistor inline with my oil pressure sensor. The resistor in a circuit will usually disperse energy as heat.
A convex lens cannot produce heat. It can focus incident heat to a smaller area so that it is more intense.
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.
