Series Circuits - All or Nothing Flashcards
In a series circuit, how are the different components connected?
In a line, end to end, between the +ve and -ve of the power supply
Which component is the only exception to this rule?
A voltmeter - always connected in parallel
What happens if you remove or disconnect one component?
The circuit is broken and they all stop working
Why are only a few things connected in series?
They’re not very handy as if one thing breaks the whole thing breaks
What happens when there are more cells in a series?
There’s a bigger supply of p.d
What is important to know about the current in a series circuit?
The current is the same everywhere
What does the size of the current depend on?
The total potential difference and the total resistance of the circuit (I = V / R)
What does the p.d for each component depend on?
It’s resistance
The total potential difference of the supply is…
Shared between components
What does the total resistance of the circuit depend on?
The number of components and the type of components used
