6. 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

7. 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

8. 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

9. 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)
