topic 1 and 2 Flashcards
Atoms can lose or gain electrons and become
ionized
Charged particles can either blank or blank each other
attract or repel each other
When there are an unequal number of protons and electrons, this builds up a
static charge
Electric current is the continuous flow of
electrons
The rate at which electrical current flows is measured in a unit called
amperes
Conductors allow electrical charges to
flow
What is another name for voltage
potential difference
Electric current will always take the
shortest path available
What is the third prong called
Ground prong
Fuses and circuit breakers are safety devices that
break the flow of electrons through the circuit if the current gets too high
what is a dry cell?
a cell that has its electrolyte in the form of a paste
What is an electrolyte
liquid or paste that conducts electricity cause it forms ions
what is a wet cell
cells that use a liquid electrolyte instead of the paste
Cells that “die” are called
primary cells
Rechargeable cells are called
secondary cells
