He frames the story with his dream of buying a house in San Francisco. To this day, just why filings stick together in the presence of a radio current is still not completely understood, but the fact remains that if a pile of metal filings are loosely placed between two electrodes and no radio frequency current is present, the resistance between the electrodes is quite high.

There was a good crowd. De Magnete, magneticisique corporibus, et de magno magnete tellure. Among Benjamin's siblings were his older brother James and his younger sister Jane. To accomplish this he had developed one of the most sensitive galvanometers of his time.

copper,aluminium,gold,silver are good conductors of we dont use gold or siver as it is uneconomical thpugh they are good conductors. Points to Remember - What you have learnt. Elements can be classified as metals and non-metals. Metals are lustrous, malleable, ductile and are good conductors of heat and electricity.

Potential difference V and electromotive force, emf. The potential difference or voltage, V between 2 points is defined as the work done, W in taking 1 C of positive charge from the lower potential to the point of higher potential.; In a circuit, it is the energy sources that supply energy, not the electric charges.

The energy that drives the free electrons around the circuit is known as emf. Many metals, like silver, copper, gold and aluminum, are good thermal conductors.

Thermal conductors are materials that heat passes through easily. Conduction, or the transfer of heat, can take place within a single material or between two objects. Heat can only travel from a hot material to a cold. Reg Consumer no.: /bill for Rs.
