What are the three chemical effects of electric current?
Some of the chemical effects of electric current are as follows :
- Bubbles of gas may be formed at electrodes.
- Deposits of metal may be seen on electrodes.
- Change of colour of solution may occur.
How current is measured?
Current is measured in Amperes (usually just referred to as "Amps"). An ampere is defined as 6.electrons (1 Coulomb) per second passing through a point in a circuit. Amps are represented in equations by the letter "I". ... This is analogous to an increase in voltage that causes an increase in current.
What are chemical effects of current?
О The passage of an electric current through a conducting liquid causes chemical reactions. The resulting effects are called chemical effects of currents. О The process of depositing a layer of any desired metal on another material, by means of electricity, is called electroplating.
What are the four effects of electricity?
Four of the major effects of electricity are the magnetic effect, heating effect, chemical effect, and electrical effect or electrical shock. Magnetic effects occurs in some devices such as door bells and buzzers. This devices create sounds because of the magnetic effect. They have electromagnets inside.
What is the magnetic effect?
Magnetic force, attraction or repulsion that arises between electrically charged particles because of their motion. ... The magnetic force between two moving charges may be described as the effect exerted upon either charge by a magnetic field created by the other.
Where is the magnetic field the strongest?
What carries the magnetic force?
electromagnetism photons magnetic-fields electric-fields virtual-particles. The force carrier for magnetic fields and electric fields are supposedly photons.
Why is force of attraction stronger than repulsion?
The attraction between magnets is a little stronger than the repulsion. That is due to the alignment of the molecular magnets in the magnet. The attraction as well as the repulsion of magnets decrease significantly with increasing distance.
What happens if you force 2 magnets together?
When two magnets are brought together, the opposite poles will attract one another, but the like poles will repel one another. This is similar to electric charges.
What weakens magnetic attraction?
Several factors can weaken the magnetism in a magnet. If a magnet is stored close to heat, strong electrical currents, other magnets, or radiation, it can lose its strength. Additionally, high humidity can corrode neodymium magnets.
What is the difference of contact force to non contact force?
A non-contact force is a force which acts on an object without coming physically in contact with it. ... In contrast a contact force is a force applied to a body by another body that is in contact with it.
What are the 3 types of non-contact forces?
- Gravitational force.
- Magnetic force.
- Nuclear force.
Is drag a non-contact force?
Drag is a mechanical force. It is generated by the interaction and contact of a solid body with a fluid (liquid or gas). It is not generated by a force field, in the sense of a gravitational field or an electromagnetic field, where one object can affect another object without being in physical contact.
Is electric force contact or non-contact?
Electrostatic forces are non-contact forces; they pull or push on objects without touching them. Rubbing some materials together can result in something called 'charge' being moved from one surface to the other.
