Ohm’s Law & Series Circuit Lab What is the relationship between Resistance and current? Inverse Relationship I = 9.98 (1/R) I = V (1/R) V = I (R) Ohm’s Law

Ohm’s Law & Series Circuit Lab What was the voltage drops across each of the resistors? What pattern did you observe? Individual Resistors had the same voltage across each and it equaled the voltage of the battery For circuits with Multiple Resistors, how does the Total Voltage compare with the individual Voltages? The voltage drop across each resistor added up to equal the total voltage Bigger Resistors drew more Voltage How did you come up with the Total Resistance when we put multiple resistors together? Added the Resistors together to get the Total

Ohm’s Law & Series Circuit Lab Rule #1: Current Constant For a Series Circuit Rule #2: Resistance Added the Resistors together to get the Total Rule #3: Voltage The voltage drop across each resistor adds up to equal the total voltage of the battery or source Bigger Resistors need more Voltage

Voltage Current Resistance Ohm’s Law Power Supplied by battery or other source Measured in Volts (V) Current Flow of electrons through the circuit Measured in Amps (A) Resistance Devices or Objects that impeded the flow of electrons (i.e. Current) Measured in Ohms (Ω)
