circuits - Flashcards
In series, voltage is…
shared between components
another word for potential difference is..
voltage
in parallel, voltage is ….
the same for each component
what is potential difference ?
the difference in potential energy that gives charge ‘the push’ causing electrons to flow
potential difference =
current x resistance
resistance is always ____ when the current changes
stable
Ohm’s Law states …
when the current flows through ohmic conductor it is directly proportionate to the potential difference (as temperature is constant)
the ____ the electrons the higher the current
faster
the ____ electrons there are the higher the current.
more
charge flow (c) =
current (a) x time (s)
what are the units for charge flow?
couloumps (C)
what are the units for current?
amps (A)
in series current is…
the same at all places in the circuit
in parallel, current is…
split into different branches
