OHM’S LAW Resistance
O HM ’ S L AW O HM ’ S L AW Ohm’s Law: Is the relationship between voltage, current and resistance.
S ERIES C IRCUITS A series circuit has only one path for the charges to follow.
C URRENT IN S ERIES C IRCUITS In a series circuit, there is only one path for the current to follow. Therefore, the current in all parts of the circuit will be the same.
R ESISTANCE IN S ERIES C IRCUITS Putting two resistors in series with one another further restricts the current flow.
P OTENTIAL D IFFERENCE IN S ERIES C IRCUITS
in any closed circuit loop, the sum of the potential difference drops through all the components must be zero.
P OTENTIAL D IFFERENCE IN S ERIES C IRCUITS
S ERIES C IRCUITS Determine the current, total resistance, and voltage drops through all the resistors in the circuit
S ERIES C IRCUITS
P ARALLEL C IRCUITS A parallel circuit is a closed circuit in which the current has more than one path, or branch, to follow
C URRENT IN P ARALLEL C IRCUITS
Kirchhoff’s current law, which states that the current entering junction must be equal to the current leaving the junction.
R ESISTANCE IN P ARALLEL C IRCUITS
P OTENTIAL D IFFERENCE IN P ARALLEL C IRCUITS Kirchhoff’s voltage law : the sum of the potential difference drops through all the components must be zero.
P OTENTIAL D IFFERENCE IN P ARALLEL C IRCUITS
P ARALLEL C IRCUITS
M IXED C IRCUITS
Analyze the circuit diagram to solve for the current and potential difference through each resistor.
