Electricity1 Flashcards
Existence and interaction of electric charge
Electricity
Positive and negative algebraic signs and measured in coulombs
Electric charge
Si unit of electric charge
Coulomb
Energy per unit charge available for conversion from a chemical, mechanical, or other form of energy into electrical energy
Electromotive force
voltage difference that represents work involved in the transfer of a unit charge
Potential difference
required a unit to move
Potential
Group of two or more cells connected together to produce electric current
Battery
Device for converting chemical into electric energy
Consisiting of a receptacle with electrodes
Cell
nonmettalic conducting medium
Electrolytes
Conductor through which a current emters or leaves a nonmettalic medium
Electrode
Negative terminal of a primary cell
Anode
Positive terminal
Cathode
Voltage
Potential difference or electromotive force express in volts
Si unit of potential difference and electromotive force
Volt
Complete path of an electric current
Circuit
Arrangements of components in an electric circuit which the same current flows through each components in turn without branching
Series
Ehich all positive terminals are connected to one conductor
Parallel
Product of potential difference and current
