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).
