Series Circuit Problems
Name ________________
Remember that in a series circuit:
 the current in every part of the circuit (is the same, adds up).
 the voltage supplied by the battery is the _______ voltage of the circuit, and the
voltage drops across each resistor (is the same, adds up to) the total voltage.
 to calculate total resistance, (add).

Parallel Circuit Problems
Name _______________
Remember that in a parallel circuit:

 the current in the branches of the circuit (is the same, adds up).

 the voltage drops across each branch (is the same, adds up to) the total voltage.

 to calculate total resistance, (add, use reciprocals).
