electricity Flashcards
1
Q
cells definition
A
provide energy for the circuit and must be added in the same orientation
2
Q
conductors definition
A
allow electrical current to pass through e.g. metal
3
Q
wires
A
usually made from copper which is a good conductor and affordable
4
Q
insulators definition
A
prevent current from passing through
5
Q
what circuits need
A
power supply (potential difference) to be complete (no gaps) and a component (something to do )
6
Q
when will a circuit not work
A
if there is a gap between the positive end of the battery and the negative end
7
Q
series circuit definition
A
one path the current can take
8
Q
parallel circuit definition
A
more than one path the current can take
9
Q
ammeters definition
A
measure the current in a circuit
10
Q
when will a current increase
A
if another cell is added to the circuit
