Electric circuits — practice question

The diagram illustrates a potential divider. As brighter light shines on the light-dependent resistor (LDR), its resistance changes. What happens to the resistance of the LDR and what happens to the current through it?

  • Aresistance decreases; current decreases
  • Bresistance decreases; current increases
  • Cresistance increases; current decreases
  • Dresistance increases; current increases
