What else can I help you with?
When charges continually shift from flowing in one direction to flowing in the reverse direction there is a what current?
Alternating current would fit this description.
When there is no current passing through a conductor you say magnetic field is zero but in a conductor charges are in motion then why is there no magnetic field?
When there is no current passing through a conductor, charges are stilll in motion, but they are disorganized and not flowing. The magnetic fields by all of those random movements cancel each other out. That is why there is no magnetic field in a conductor with no current, even though there is movement in the charges.
Does static electricity electrical charges that are not in motion?
Yes, static electricity refers to electrical charges that are not flowing as a current, but rather remain stationary on an insulating material or object. This buildup of charge occurs when certain materials rub against each other, causing electrons to transfer and create an imbalance of positive and negative charges.
Does material travel faster when the river is flowing down a steep slop or across flat land?
Material will travel faster in a river flowing down a steep slope. As the water slows down, the material will also slow down.
When charges continually shift from flowing in one direction to flowing in the reverse direction what current is there?
When charges continually shift direction, alternating currents (AC) are present. AC involves charges oscillating back and forth in a circuit, with the direction changing periodically. This is different from direct current (DC), where charges flow consistently in one direction.
The opposition to the movement of charges flowing through a material?
Resistance is the opposition to the movement of charges flowing through a material. It is measured in ohms and varies depending on the material and its properties.
What is the opposition to the movement of charges flowing through a material?
Resistance
What is the opposition to the movemnet of charges flowing through a material?
The opposition to the movement of charges flowing through a material is called resistance. Resistance is caused by collisions between the moving charges and atoms in the material, which convert some of the electrical energy into heat. It is measured in ohms (Ω).
What is the opposition to the movement of charge flowing through a material?
Resistance
What opposing force must be overcome by charges flowing in electronic currents?
The resistance in a material is the opposing force that charges flowing in electronic currents must overcome. Resistance is caused by collisions between moving electrons and the atoms of the material, which results in the conversion of electrical energy into heat. This opposition can slow down the flow of charges and reduce the efficiency of the electronic circuit.
What opposing force must be overcome by charges flowing in electric circuits?
The opposing force that charges flowing in electric circuits must overcome is resistance. Resistance is caused by factors such as the material through which the charges are flowing, the temperature of the material, and the dimensions of the material. It impedes the flow of charges and results in the conversion of electrical energy into heat energy.
Movement of heat energy by flowing material?
Convection
What is the name for heat flowing through solids?
Conductors
What is a material that blocks the flow of electric charges?
An insulator is a material that blocks the flow of electric charges. Insulators have high resistance to the flow of electrons and do not conduct electricity easily, making them ideal for preventing electric charges from flowing. Materials such as rubber, plastic, and glass are common examples of insulators.
What happens to the object when electricity travels through it?
When electricity travels through an object, it causes the movement of electric charges within the material. This movement generates heat and light, which can impact the object's temperature or produce electromagnetic fields. The specific outcome depends on the properties of the object and the amount of electricity flowing through it.
What keeps charges from flowing easily?
The resistance in a material impedes the flow of charges, making it difficult for them to move freely. Resistors, insulators, and other obstacles in the circuit can restrict the flow of charges by converting some of the electrical energy into heat or other forms of energy.
A material in which charges is cannot easily move?
An insulator is a material in which charges cannot easily move due to the lack of free electrons. Examples of insulators include rubber, glass, and plastic. Insulators are used to prevent electric current from flowing through them, making them good materials for electrical insulation.
