Circuits with more than one
resistor, then Watt happens?
Series and Parallel are the 2
ways of connecting multiple
resistors
Series Circuits

In a Series Circuit there is only one path
for charges to flow so the current (I) is
the same everywhere.
Series Circuits


The total Resistance is the sum of the 2
resistor values: Rtotal = R1 +R2
To Find the Current (I) , use I = V/Rtotal
Series Circuits

The battery puts in Volts (energy =
skittles) and each of the resistors uses
up some of the Volts. Together the 2
resistors use up the total Volts that the
battery puts in.

Parallel Circuit

In a parallel circuit both resistors get
the same amount of voltage as the
battery puts in.
Parallel Circuit


Now moving charges (current) has a
choice of which path to take.
The current (I) must be conserved so I1
=I2 + I3
Parallel Circuit


Rule for finding the total resistance in
parallel: 1/Rtotal = 1/R1 + 1/R2
Use this total resistance to find the
current (I) supplied by the battery
Parallel Circuit
