A short circuiting of a dynamo by, or any connection of its coils with, the iron magnet cores or other iron parts.

Iron deposited by electrolytic action. Various baths are employed for its formation. (See Steeling.) It has very low coercive power, only seven to ten times that of nickel.

A metal; one of the elements; symbol, Fe; atomic weight, 56; equivalent, 28 and 14, ; valency, 4 and 2. It is a conductor of electricity. The following data are at 0° C. 32° F., with annealed metal. Specific Resistance,   9.716 microhms. Relative Resistance.   6.460 Resistance of a wire, (a) 1 foot long weighing 1 [...]

The products of decomposition produced in any given electrolysis are termed ions, the one which appears at the anode or negative electrode is the anion. The electrode connected to the carbon or copper plate of a wet battery is an anode. Thus in the electrolysis of water oxygen is the anion and hydrogen is termed [...]

A term in medical electricity, denoting the part of a nerve through which a current is passing.

An apparatus for interrupting a current which passes through an electromagnet near and facing one of the limbs of a tuning fork. The circuit is made and broken by the vibrations of another tuning fork through which the current passes. The second one is thus made to vibrate, although it may be very far off [...]

A circuit breaker. It may be operated by hand or be automatic. (See Circuit Breaker–Circuit Breaker, Automatic–and others.)

A process used in getting a closer approximation to the truth from two varying observations, as of a galvanometer. The process varies for different cases, but amounts to determining an average or deducing a proportional reading from the discrepant observed ones.

A conductor connecting the two poles of a battery or current generator; the external circuit in a galvanic circuit.

Acting at intervals, as an intermittent contact, earth, or grounding of a telegraph wire.
