The complete explanation probably involves quantum mechanics, but for an intuitive explanation, simply imagine that electrons move through a metal (for example), and that now and then, some of them collide with atoms, wasting energy from the electric current - and heating up the metal (by making the atoms move faster).

How do resistors work in a circuit to regulate the flow of electric current?
Resistors work in a circuit by impeding the flow of electric current, which helps regulate the amount of current that passes through the circuit. They do this by converting electrical energy into heat energy as the current passes through them, which reduces the overall flow of current in the circuit. This helps control the voltage and current levels in the circuit, allowing for proper functioning of electronic devices.
How do resistors work and what is their role in an electrical circuit?
Resistors are electronic components that limit the flow of electric current in a circuit. They work by converting electrical energy into heat. Their role in an electrical circuit is to control the amount of current flowing through different parts of the circuit, helping to regulate voltage levels and protect sensitive components from damage.
What happens to energy in a curcuit?
In a circuit, electrical energy is converted into other forms of energy as it flows through components like resistors, capacitors, and inductors. Some energy may be dissipated as heat by resistors, while capacitors and inductors store and release energy in the form of electric and magnetic fields. Overall, energy is conserved in a circuit, but its form may change as it interacts with circuit elements.
Why do resistors get hot?
Resistors get hot because they convert electrical energy into heat while resisting the flow of electricity. This heat is a byproduct of the resistance in the circuit and can cause the resistor to become hot to the touch.
Does resistors absorb energy?
Resistors do not absorb energy in the sense that they store or convert energy. They dissipate electrical energy in the form of heat, which is a byproduct of resisting the flow of current through a circuit.
Why does a circuit warm up when it has electric current flowing in it?
Resistors dissipate energy in the form of heat.

Why do you use resistor in electronics?
we use resistors to offer opposition to the flow of electric current. Resistors absorbs power from the circuit and convert it into heat that is why they are normally rated for the maximum amount of power that they can salfely handle

How could electricity set a fire?
Electricity in electric circuits produce heat and when a circuit goes wrong the heat can escalate to the point where it causes combustion in the materials adjacent to it. This causes fires.
Is electric heater require oxygen to burn?
No, electric heaters work by running electric current through resistors which produces heat. same as an element on an oven range top.
What is produced when there is resistance to the flow of electrons?
It depends on the nature of the device acting as the resistor. All basic circuit components act as resistors. Resistors dissipate energy from the current in the form of heat. Capacitors store energy in a electric field. Inductors create a magnetic field.In practice in general, heat dissipation is present in most resistive devices (including circuit wires). So common, in fact, that we call it "internal resistance". But that is effectively how we use electricity: by resisting its flow.
How are light emitting diodes able to produce so much light but without producing any heat?
The electrons in the electric circuit excite the atoms of the diode efficiently, not much energy is wasted (in the form of heat).
Does resistors absorb energy?
Resistors do not absorb energy in the sense that they store or convert energy. They dissipate electrical energy in the form of heat, which is a byproduct of resisting the flow of current through a circuit.
What type of resistors carry relatively high electric currents?
Power resistors are designed to carry high electric currents due to their ability to dissipate heat effectively. These resistors are commonly used in applications where high power levels need to be handled, such as in power supplies, industrial equipment, and power electronics. They often have a large physical size and are built to withstand the heat generated by the current passing through them.
