Chapter 9 Flashcards
Physics
What is current?
rate of current flow(electrons)
What is voltage?
Potential difference force between two points
The current throughout the series circuit is the same.
True
The sum of the voltage of each
component is equal to the voltage
supplied by the cell in a parallel circuit.
False
The sum of the current in each branch
is equal to the current of the cell in a series circuit.
False
The voltage of each branch is equal to
the voltage supplied by the cell in a parallel circuit.
True
If you add more components to a circuit……….
Current decreases
What is resistance?
how easy/difficult it is for the current to flow
Symbol to measure resistance?
Ω (ohms)
Formula for resistance?
R=V/I
Imagine you are an electron in a circuit. Where do you start your journey?
Negative terminal
What happens when there is more resistance in a circuit?
less current flow/current decreases
