Quiz  /  Resistors in Series and Parallel

  • 1. 
    What is the total resistance of a circuit called?

  • Equivalent resistance
  • Absolute resistance
  • Unlimited resistance
  • Comprehensive resistance

  • 2. 
    Which of the following best describes resistors connected in parallel?

  • Resistors connected across from one another
  • Resistors connected end-to-end
  • Resistors that connect to capacitors
  • Resistors that aren't in the same circuit

  • 3. 
    Which of the following best describes resistors connected in series?

  • Resistors connected across from one another
  • Resistors connected end-to-end
  • Resistors that connect to capacitors
  • Resistors that aren't in the same circuit

  • 4. 
    What formula would be used to calculate the equivalent resistance if R1 and R2 were connected in series?

  • R = R1 + R2
  • R = R1 * R2
  • R = 1/R1 + 1/R2
  • 1/R = 1/R1 + 1/R2

  • 5. 
    What formula would be used to calculate the equivalent resistance if R1 and R2 were connected in parallel?

  • R = R1/R2
  • 1/R = 1/R1 + 1/R2
  • R = R1 * R2
  • R = 1/R1 + 1/R2

  • 10. 
    When you have a circuit with both series and parallel resistors, what do you do first when calculating the equivalent resistance?

  • The series resistors
  • The parallel resistors
  • It doesn't matter which you do first
