When the current in a nearby coil changes, the magnetic flux associated with it changes and an induced emf is produced in the other coil.Hence, induced current is produced.
a current carriying wire in the presence of magnetic feild produce a force.applyied to motors
This only works in the case of an alternating current. The coil containing electricity produces a magnetic field; a CHANGING magnetic field induces a voltage in nearby conductors.
A resistor placed across the power line: I squared R (current x current x resistance) = heat in watts.
Metal is an excellent conductor of electricity. So a metal paper clip placed in an electric circuit will conduct whatever current may be in that circuit. If the current is very large, the paperclip may get hot.
Table salt is NaCl, when placed in water. The elements separate into Na+ and Cl-. The + and - ions connect the electrical current.
wind turbines can be placed, and the spinning of the propeller turns some magnetic thing against a coil, producing electricity.
When an incandescent light bulb (the normal round ones that Thomas Edison invented) is placed into a "hot" circuit, (meaning there is electricity flowing through it), the electricity passes through the filament (little metal wires) on the inside. As the electricity passes through it, the wires heat up and make a chemical reaction causing light to be emitted.

water is a conductor of electricity so when a live wire is placed into water the current can spread out through the water.
Whenever a charge passes through a conductor, a magnetic field is produced. Hence, whenever a current carrying conductor is placed in a magnetic filed, it will experience a force whose direction is determined by Fleming's left hand rule.
The name of the song is What About Love? and the artist is Lemar.
After Helens passing, the burial urn containg her ashes was placed next to Annie's and Polly's at the National Cathedral in Washington, D.C. ~CaitlinDavis;)
You need two identical beakers containg the same volume of water, placed in the same position.
Being that the capacitor appears as a short during the initial charging, the current through the diodes can momentarily be quite high. To reduce risk of damaging the diodes, a surge current limiting resistor is placed in series with the filter and load.
Electricity has different meanings. It means production of electric charges in one way and producing electric current the other way. In case of current there are two types: direct current and alternating current Static electric charges are produced by frictional method. Example: when we rub glass rod with a silk cloth or rubbing a plastice scale with a polythene plastic paper charges are produced. Static charges can be produced by induction method too. Ex: When a positively charged rod is brought near by a metallic sphere its near end would have negative charge and the farther end would have positive charge. This static charge is the basis for lightning process happening in between clouds and the clouds and the ground. Direct current is produced by the chemical reactions taking place in between the electrolyte and the electrodes being used. Ex: lead acid accumulator, other dry cells and chargeable alkaline cells. Now a days we use solar energy to get converted into electricity with the help of photovoltaic cells. Alternating current is generated by electromagnetic induction technique. In just a cycle dynamo by the rotating the wheels we rotate the axle of the small device in which a coil is placed in a permanent magnet. So as coil gets rotated an alternating emf is induced. But very large emf is produced in the same technique by rotation the armature in a field magnet. Such rotation will become possible with storing water at greater levels as we do in case of dams. So electricity is produced near by water reservoirs. The same rotation will be possible by passing steam under high pressure over the arcs of the wheels attached to the armatures. Production of steam is by heating. Heat is drawn from coal hence thermal electricity being produced near by coal mines. Otherwise heat is got from the fission of atomic nuclei and that is termed as nuclear reactor.
