Worksheet #1: Basics & Coulomb’s Law
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
Ohm’s Law
• Voltage
– 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)

When we want to diagram circuits we will
use specific symbols to represent different
devices in the circuit

• Try drawing a circuit with:
– A power supply
– 2 resistors
– 1 ammeter
– 1 volt meter across 1 of the resistors.
