For the resistor, by definition, this component does not have the ability to store energy, if not all of the energy that is given, is transformed (usually heat).
(58) Mechanical energy: Kinetic Energy: Energy stored in a mass of 1 kilogram moving with a velocity of 1 meter per second possesses 1/2 Joule of kinetic energy. (59) Another unit for energy is calorie: calJoules Potential energy: Energy stored in a spring () of stiffness or compliance is (60)
While resistors can be involved in energy storage circuits by controlling energy release from components like capacitors or inductors, they do not retain energy for later use. Instead, resistors are designed to modify
We have seen that inductors and capacitors have a state that can decay in the presence of an adjacent channel that permits current to flow (in the case of capacitors) or resists
A resistor, commonly regarded as a passive electronic component, primarily dissipates energy as heat rather than store it, contrary to elements such as capacitors and inductors that effectively manage energy storage.
While resistors can be involved in energy storage circuits by controlling energy release from components like capacitors or inductors, they do not retain energy for later use. Instead, resistors are designed to modify current flow, ensuring that energy is efficiently managed throughout the circuit. HOW DOES TEMPERATURE AFFECT RESISTOR PERFORMANCE?
When electric current flows through a resistor, some of the energy carried by the current is dissipated as heat, effectively reducing the current. The amount of current that a resistor can reduce depends on its resistance value: the higher the resistance, the more it limits the current.
The very nature of a resistor causes it to dissipate energy in the form of heat when attached to a power source. But if you connect a device to a power source through a resistor you can regulate the current through the device this way.
I''m a beginner who just learned about resistors. As you guys all know, their job is to dissipate energy in the form of electricity. This makes sense, but it made me wonder: are there any types of resistors that don''t get rid of the energy as heat, but instead store it or use it somewhere else?
Let''s cut to the chase: resistors can''t store energy. They''re the snackers of the electronics world – constantly munching on electrical energy and converting it into heat, never saving any for later.
Yes, resistors will transform electrical energy to heat, which is considered "internal", however, you will not find many treatments of electrical circuits in terms of thermodynamics.
Resistor can’t store energy. Neither can be a source on its own. Resistor always dissipates energy in the form of heat. Other elements like inductor and capacitor store energy in the magnetic and electric fields respectively. Examples for active devices are operation amplifier (OPAMP) etc. A resistor consists of two terminals.
Yes, resistors will transform electrical energy to heat, which is considered "internal", however, you will not find many treatments of electrical circuits in terms of thermodynamics. The reason for that is because electrical circuits are extremely far away from thermal equilibrium and thermodynamics has very little useful things to say about that.
Resistors are commercially available with values in the range from 10 mΩ to 1000 GΩ (i.e. from 10–2 Ω a 10+12 Ω), and different types may dissipate, without excessive self-heating, power in the range from 1/8 watt to hundreds watt.
@GM: No, because in any moment in which there is a voltage across the resistor and a current flowing through it, energy is lost. A resistor will lose it through heat. Something like a motor will lose it through mechanical work. A capacitor or inductor will lose it by building up energy in its field.
Can anyone tell me what really do a resistor? The heat generated is the wattage dissipated, namely W = V I, so if the resistance is lower, the current will be higher, and if the voltage remains the same, you get more heat.
A resistor will lose it through heat. Something like a motor will lose it through mechanical work. A capacitor or inductor will lose it by building up energy in its field. For a resistor, it will generate heat - there's no other way for it to behave.
