Topic 21 - series and parallel circuits Flashcards
1
Q
what are the features of a series circuit
A
Components connected in a line end to end
to the +ve and -ve
Ammeters are always connected in series
Current is same everywhere
2
Q
what are the features of a parallel circuit
A
Each component is SEPARATELY connected to the
+ve and -ve
Voltmeters are always connected in parallel
Potential difference is same across all components
3
Q
how do you work out the total resistance in a series circuit
A
add the two resistors together
4
Q
how do you work out the resistance in a parallel circuit
A
its less than the smallest number resistor
