Series Circuits Flashcards
1
Q
Potential Difference
A
Amount of energy a cell can provide to push a certain amount of electrons through a circuit
2
Q
Electrons lose energy
A
Transfer it to resistor
3
Q
Electrons gain energy
A
Chemical energy from battery
4
Q
PD is measured by
A
Voltmeter, high internal resistance, parallel
5
Q
Cannot connect voltmeter in series
A
Resistance is too high, will affect current
6
Q
Ammeter
A
Series, small internal resistance, does not affect current
7
Q
+ cells
A
+ current, PD
8
Q
+ resistance
A
Current decreases
9
Q
Sum of PD across resistors
A
PD across battery
10
Q
High resistance
A
Large PD
11
Q
Low resistance
A
Small PD
12
Q
Resistors are
A
Potential dividers
13
Q
Series
A
Only one path for electric current to move through circuit
