The term expressing the connection of several pieces of electrical apparatus in parallel with each other so that the current is divided between them.
The unit of resistance. It is arbitrarily taken as the resistance of a column of mercury, one square millimeter in cross sectional area and 106 centimeters in height.
The same meaning as multiple. Parallel circuits are those which start at a common point and end at a common point.
The collection of hydrogen upon the positive electrode of a primary cell with a consequent loss of voltage.
Voltage or electrical force.
The quality of an electrical conductor whereby it opposes the passage of an electric current. The unit of resistance is the ohm.
A variable resistance to regulate the strength of an electric current.
Opposed to parallel or multiple. Instruments in series are so connected that the current passes from one to the other and does not divide.
An air gap or open space between two electrodes for the passage of a high voltage discharge.
See accumulator.
