4 - Electric circuits Flashcards
1
Q
Oppositely charged objects attract each other because…
A
electrons in the air travel towards the positively charged matter, creating a flow of electrons between them.
2
Q
Ammeters are connected in…
A
series.
3
Q
Voltmeters are connected in…
A
parallel.
4
Q
An LED is a diode that…
A
emits light when current passes through.
5
Q
A thermistor is a…
A
temperature dependent resistor
6
Q
In an LDR, resistance decreases if…
A
light intensity decreases.
7
Q
In a series circuit, current is…
A
the same, potential difference is shared.
8
Q
In a parallel circuit, current is…
A
shared, potential difference is the same.
9
Q
More resistors in a parallel circuit equals…
A
less resistance because there are more pathways for current to flow.
