Review of Voltage and Current Labs
In a SERIES circuit:
 BRIGHTNESS of lights _____________________ as you add more lights in series
 Potential energy (voltage) ______________ by the loads (there is less potential energy available
to each load).
Vs =
Is =
 CURRENT is ____________________ through the loads (electrons travel: __________________)
 CURRENT ____________________ (for the whole circuit) as you add more loads (more bumps)!!!
 each load adds more _________________ to the circuit
In a PARALLEL circuit:
 BRIGHTNESS of lights ________________________ as you add more lights in parallel
 Electrons travel __________________. Each load receives the same potential energy.
 Voltage is the ___________ across all loads if they are the same.
Vs =
Is =
 CURRENT of the source is _____________ of
the currents at each load.
 electrons more paths to travel, each receiving the ___________ amount of current.
 so CURRENT (source) ________________ as you add more loads!!!

Personal notes:
PRACTICE
Determine the CURRENT (I) and/or the VOLTAGE in each of the following circuits
 write the voltage at the source and/or wherever there is a blank (__ V) at the load(s)
 write the current from the source and/or wherever there is a blank arrow () at the load(s)
