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


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

The voltage drop across each resistor added up to equal the total voltage

Bigger Resistors drew more Voltage

For circuits with Multiple Resistors, how does the Total Voltage compare with the individual Voltages?

How did you come up with the Total Resistance when we put multiple resistors together?

Added the Resistors together to get the Total


Rule #1: Current

Constant For a Series Circuit

The voltage drop across each resistor adds up to equal the total voltage of the battery or source

Bigger Resistors need more Voltage

Rule #2: Resistance

Rule #3: Voltage

Added the Resistors together to get the Total

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)

Wire

VAA

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

Schematic Diagrams

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