current in series and parallel Flashcards
1
Q
what is required for current to flow?
A
a source of potential difference and a closed circuit
2
Q
the amount of current is dependent on?
A
potential difference and resistance
3
Q
what happens if you double the potential difference but keep the resistance the same?
A
the current will double
4
Q
what happens to the current if you increase the resistance but keeping the potential difference the same?
A
the current will decrease
5
Q
in a series circuit what is the current like?
A
the same everywhere
6
Q
what is an advantage of connecting the lamps in parallel as oppposed to connecting them in series?
A
if one of the lamps breaks, the circuit will still work as the other bulb will still work
