1. ELECTRIC CELLS AS ENERGY SYSTEMS :
-TERMS TO KNOW HOW TO DEFINE:
1. CELL
A device which converts chemical energy into electrical energy.
A chemical system in which certain chemical reactions cause the flow of
electricity which is brought about by means of an external circuit.
,
,2.BATTERY
A battery is a
group of two or
more electric cells
that are
connected
together.
, 3.CIRCUIT BREAKER
A safety device that automatically switches off the flow of an electric
current when an overload or short circuit occurs.
can be activated when too many plugs are plugged in a single plug.
4.OHMS
The unit of measuring resistance
5.FUSE
A safety device in an electric circuit that melts if the current exceeds a
safety limit.
6.CONDUCTOR
Any material which allows the passage of electricity through it.
7.RESISTOR
An electrical component that limits or regulates the flow of electrical
current in an electronic circuit.
8.ELECTROLYTE
