A. A circuit with 3 resistors in series with a 12 V cell.
B. A circuit with 3 resistors in parallel with a 6.0 V cell.
C. A circuit with a single resistor in series with 2 resistors
that are in parallel with a 9.0 V cell.
Review

The total potential supplied by the source must
be “used up” by the components of the circuit.

The sum of the potential drops across each
component in a series circuit will be equal to
the total potential supplied by the source

The electrons going through parallel branches
will each experience the same drop in potential
by the time they meet up again in the main
circuit
Kirchoff’s Voltage Rule


The total current passing through a circuit
depends on the total resistance. Current
leaving the potential source is the same as the
current entering the potential source (it’s not
“used up”)
Current must pass equally through all
components in series with each other

When current reaches a junction, it will split.

The sum of the currents entering a junction will
be equal to the sum of the currents exiting a
junction
Kirchoff’s Current Rule
