Why does electrical resistance cause heat to be produced?
When current flows through a material with resistance, electrical energy is converted into heat energy due to the collisions between electrons and atoms in the material. This increased kinetic energy in the material causes the temperature to rise and heat to be produced as a result of resistance.
How does resistance affect the life of a conduction system?
Resistance in a conduction system, such as electrical wiring, can cause a decrease in the flow of current and lead to loss of energy in the form of heat. It can also result in issues like voltage drops and inefficiencies in the system. High resistance can cause overheating and potential damage to the components.
What are the energy change for an electric fire?
The energy change for an electric fire involves the conversion of electrical energy into thermal energy and light energy. When electricity flows through the heating element of the electric fire, it encounters resistance, which causes the electrical energy to be converted into heat energy. This heat energy is then radiated out as warmth and light energy, providing both heat and illumination in the surrounding area.
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.
What device turns sound energy into electrical energy?
A microphone is a device that converts sound energy into electrical energy. Sound waves cause a diaphragm in the microphone to move, which then generates an electrical signal that represents the sound.
What happens when removing Thermal Energy from gold?
Removing thermal energy (or, to be accurate INTERNAL energy since in thermodynamics thermal energy is a deprecated term) will usually cause it to get cooler. If it is near a phase boundary it may, instead cause some of it to change phase (solidify from liquid for example). Since electrical resistance is dependent on temperature, it will also lower the electrical resistance.
What is the main cause of wasted energy in the field of transportation?
Idle time.
Why does electrical resistance cause heat to be produced?
When current flows through a material with resistance, electrical energy is converted into heat energy due to the collisions between electrons and atoms in the material. This increased kinetic energy in the material causes the temperature to rise and heat to be produced as a result of resistance.
Electric current flows in a wire which is opposed by what?
Electric current flowing in a wire is opposed by electrical resistance. This resistance is caused by factors such as the material of the wire, its length, and its cross-sectional area. It results in the conversion of electrical energy into heat.
How does electric resistance relate to energy transformation?
Power in a circuit is inversely proportional to the resistance, all other things being equal. Voltage equals amperes time resistances, so amperes equals voltage divided by resistance. Watts equals voltage times amperes, so watts equals voltage squared divided by resistance.
How does resistance affect the life of a conduction system?
Resistance in a conduction system, such as electrical wiring, can cause a decrease in the flow of current and lead to loss of energy in the form of heat. It can also result in issues like voltage drops and inefficiencies in the system. High resistance can cause overheating and potential damage to the components.
Is television an electrical or electronic device?
electrical and electronic is the same thing your TV uses electricity
What is the cause of resistance and how the resistance and how the resistance of a wire can be determined?
Electrical resistance can be determined by the equation that defines resistance - Ohm's Law. Just divide the voltage across a resistor, by the current passing through it.
What are the energy change for an electric fire?
The energy change for an electric fire involves the conversion of electrical energy into thermal energy and light energy. When electricity flows through the heating element of the electric fire, it encounters resistance, which causes the electrical energy to be converted into heat energy.

Would cause high resistance in a closed electrical circuit?
corroded/dirty connections
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.
What happens to an electrical circuit when there is unwanted resistance in it?
a common cause of this type problem is corrosion at a connector.
