What is difference between electro motive force of a bettary and emf produced due to change in current in conductor?
workdone on unit postive charge by bettary is called electro motive force .it is not a force but traditionaly used as force to carrying charge from lower potential to higher potential. when current change in a coil then megnatic flux is change due to which emf is induced . this emf is a effect of changing current while electro motive force is a work donr by bettary to carry out the current in a wire
What makes a skyscraper stand up?
they have an electro megnetic current that rises from the north pole to the south pole
When can voltage be induced but not current?
"Induced" is the verb you are looking for. A current is induced in the secondary circuit by the current in the first changing, provided both conductors are close enough for the driving current's electro-magnetic field to enclose the second conductor. Note that word "changing". Direct current produces a field but that remains constant and does not induce a secondary current, as a.c. does.
What is the potential difference between two points in a circuit is called?
Voltage drop
Open circuit emf of a cell?
ELECTROMOTIVE MAGNETIC FORCE emf measured as volts . It does not guarantees a current or power but just the force is present. With a load it may disappear
What does the electro magnet prove about electricity?
An electro magnet proves that Electricity and Magnetism always co-exist in nature
What is made by coiling wire around iron and passing an electric current through it?
pass electricity through the wire and you'll have an electro magnet.
How you can make electricity?
The colloquial term electricity means the possibility of the flow of electric current which in turn gets converted into heat, light, mechanical, sound etc etc., The flow of current is possible only when a potential difference or electro motive force is generated. This generation of emf is possible by the following means. Mechanical - generator Thermal - thermo couple Chemical - electrical cells
What are the uses of electro magnet?
The most common uses of an electro magnet begin with the harnessing of electricity in windmills.
What is chemical effect of electricity?
it is electrolysis/ electro dialysis
What happens when there is a current in the ignition current?
When a electro magnet is formed
Differentiate between potential difference and electro motive force?
The difference between potential difference and electro motive force is that potential difference never remains constant whereas the electro motive force always stays constant.
What is an example of electricity and magnetism being used?
An electro-magnet.
How are electro magnet different from permanent magnet?
Electro magnets differs from permanent magnet because it requires electricity. A simple electro magnet consists of an iron rod wrapped in a coil of copper and when electricity flows through the copper, a magnetic field is formed.
What is electro chemistry?
Chemistry involving electricity. Chemistry of the cells that produce an electrical current. Also the chemistry of using electricity to cause reactions, like decomposition and purification of compounds, or electroplating of thin layers of metals for mostly decorative purposes.
What does the medical terminology combining form electro- mean?
Electricity, electric
