Conductors
Insulator
materials that offer a high resistance to current flow
Multimeter
electric instrument designed to measure 2 or more electrical quantites
a drawing that uses only symbols to show how components are connected together
Electric Chemical Cell
any material that offer very little resistance
contains 2 or more loads but only one path for circuit to flow
Semi-conductor
Series Circuit
potential energy difference ( electrical pressure )
an element with 4 valence electrons
Voltage
flow of electrons through a closed path conductor
Schematic Diagram
converts light energy into electric energy
electronic device used to control the flow of current
Resistor
Current
Photovoltaic
Resistance
opposition to current flow
converts chemical energy into light energy
