Part 18 (1/2)

2 The electro-th multiplied by the resistance

3 The resistance is equal to the electro-th

Overload In a motor an excess of mechanical hich causes the armature to turn too slowly and produces heat

Phase One complete oscillation The special form of a wave at any instant, or at any interval of time

Plate, Condenser In a static lass and revoluble

Plate, Negative The plate in a battery, such as carbon, copper or platinu, Electro- Theone metal with another by electrolysis

Polarity The peculiarity, in a body, of arranging itself with reference to netic influence

Parallel When a nurouped together That is to say, as the carbon plates, for instance, are connected with one terminal, and all the zinc plates with the other terminal

Polarization When the cell is deprived of its electro-motive force, or any part of it, polarization is the result

It is usually caused by coating of the plates

Porosity Having small interstices or holes

Positive Current One which deflects a needle to the left

Positive Any current flowing from the active eleative electricity flows from the carbon to the zinc

Potential, Electric The pohich perfory That form of force, which, when liberated, does or performs work

Power Unit The volt-amperes or watt

Primary The induction coil in induction machines, or in a transformer

Push button A thumb piece which serves as a switch to close a circuit while being pressed inwardly

Quantity Such arrangeest amount of current

Receiver An instruraphy which receives or takes in the sound or impulses

Relay The device which opens or closes a circuit so as to admit a new current which is sent to a more distant point

Repulsion, That tendency in bodies to repel each other when Electric si back to its former condition or position Electricity has resilience

Resistance The quality in all conductors to oppose the passage of a current

Resistance Coil A coil e of a current to a greater or less degree
