Resistors

• What remains constant for a simple resistor?

  The value of R
• What does a simple resistor produce on an I/V graph?

  A straight line
• What type of resistor is described in the material?

  An ohmic resistor
• How is the current through an ohmic conductor related to the potential difference?

  It is directly proportional
• What does the constant resistance in a circuit imply about the current changes?

  Current changes as the potential difference changes
• What is the relationship between current and potential difference in an ohmic resistor?

  • Current is directly proportional to potential difference
  • Resistance remains constant
  • Ohm's Law applies: V = IR
• What is the term for the difference in potential across a resistor?

  Potential difference
• What does the term "current" refer to in this context?

  The flow of electric charge
• What happens to the resistance of an ohmic resistor when the temperature is constant?

  It remains constant
• How does the potential difference affect the current in an ohmic resistor?

  Higher potential difference increases current
• What are the key characteristics of an ohmic resistor?

  • Constant resistance
  • Follows Ohm's Law
  • Produces a linear I/V graph
