Series and parallel circuits — practice question

The graph illustrates the way the resistance of a thermistor changes with temperature. The thermistor is at a temperature of $10\,^{\circ}\text{C}$ and is linked in series with a fixed resistor whose resistance is $20\,\Omega$. What is the total resistance of the two components together?

  • A$16\,\Omega$
  • B$20\,\Omega$
  • C$80\,\Omega$
  • D$100\,\Omega$
