What else can I help you with?
Why do you get a shock after walking across carpet?
Walking across carpet can build up a static charge on your body due to the friction between your feet and the carpet. When you touch a conductive object, like a doorknob, the excess electrons from your body discharge, causing a shock.
Do 2 things have to touch in order to have force between them?
No, two objects do not necessarily have to touch in order for a force to act between them. Forces such as gravitational, magnetic, and electric forces can act over a distance without requiring physical contact between the objects.
What is connecting a circuit for safety precaution to earth?
For various reason some charges may accumulated on an electric equipment. If any personal touch it he/she may get shock. That is why an extra path is provided as ground connection to remove these charges from electric body to the Earth. ========================================================== I was answering contemporaneously, the above answer is correct :-) If two points are charged and they are connected by a perfect conductor, the current flowing between the two points depends on the potential due to the charge difference. The current flows moving electrons from the negative to the positive element up to the moment in which the charge difference is nullified and no current flows due to the presence of no potential difference. If I connect a charged element to a very large, uncharged body, almost all the charge of the charged element is discharged towards the large body, creating a current burst. This happens when I touch with my body a charged element in a circuit: my body is big and neutral and it works as a sort of zero potential element, so that all the charges are discharged towards my body in a current burst that can be quite dangerous. Earth is much bigger with respect to my body, if I create a connection between the circuit and the earth that acts as a potential reference, if I touch the circuit I am at the same potential of earth, at zero potential, but no discharge happens since all possible charges have been already discharged towards Earth.
What happens when two objects that have different temperatures touch?
Heat will flow from the object that has the higher temperature, to the one with the lower temperature. This will continue until equilibrium is reached, i.e., both objects have the same temperature.
How are magnetic poles and electric charges similar?
Main similarity: Like charges repel each other, different charges attract each other.Main difference: Magnetic "charges" can't be separated. At least, so far it has not been achieved.
What two charged objects are made to touch each other and then separate?
In contrast to the attractive force between two objects with opposite charges, two objects that are of like charge will repel each other. That is, a positively charged object will exert a repulsive force upon a second positively charged object. This repulsive force will push the two objects apart.
How can you tell when an object has been statically charged?
You can tell when an object has been statically charged if it attracts or repels other objects, causes a spark when touched, or gives you a mild shock when you touch it. Objects can become statically charged through friction or contact with other charged objects.
What happens when two similer objects which are charged are brought near to each other?
If the charges are of the same sign (for instance, both have a negative charge), they will repel one another. If the charges are opposite (one positive, one negative), they will attract one another. If the objects actually touch one another, the charges may cancel, in part or totally.
What happens when two objects with dissimilar electrical charges touch?
Electricity passes between them until the dissimilar charges become equal
What would happen if you touch the knob of a positively charged electroscope with another positively charged object?
Like charges repel. Unlike charges attract. Therefore, you would expect them to repel each other.
What Charged objects do not have to what to exert a force on each other?
Charged objects do not have to physically touch each other in order to exert a force on each other. The force between charged objects can be exerted through electromagnetic fields that extend through space. This force is known as the electrostatic force.
What is the result of two objects with disimilar electrical charges touching?
When two objects with dissimilar electrical charges touch, electrons will flow from the object with the more negative charge to the object with the more positive charge until both objects reach equilibrium and have similar charges. This process is known as charging by contact.
If your hand were negatively charged and you touched a neutral doorknob which direction would negative charges move?
If your hand is negatively charged, negative charges will not move when you touch a neutral doorknob. This is because the doorknob is neutral and does not have a charge imbalance to attract charges in any particular direction.
What will happen if a negatively charged object is brought near a suspended positively charged object?
The positively charged object will be attracted towards the negatively charged object due to the electrostatic force between opposite charges. The suspended object may move closer to or even touch the negatively charged object, depending on the strength of the charges and the distance between them.
What happens when you touch a charged object?
When you touch a charged object, the excess charge will flow between you and the object, leading to a transfer of electrons. This can result in a mild shock or spark, depending on the amount of charge and the conductivity of the objects involved.
How do electric charges affect other ones?
An electric charge responses differently to other electric charges. When they connect (every touch, or even one getting closer to the other), there will be an electrostatic response. Either an attraction, meaning they "want" to get closer, or an electrostatic repulsion, meaning they "want" to get away from one another. The electric charges can be in any matter, not in a single one, but even in two separate matters.Each charge can be positively charged (it will experience a repulsion to other positively charged matters), and it can also be negatively charged (the substance that is charged will experience an attraction to other positively charged substances. However, it will be repelled from other negatively charged substances).
What is a charge transfer between objects that touch each other called?
A charge transfer between objects that touch each other is called conduction. This occurs when electrons flow from a charged object to a neutral object when they come into contact.
