Electric circuits — practice question

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

  • Aresistance of LDR decreases; current in LDR decreases
  • Bresistance of LDR decreases; current in LDR increases
  • Cresistance of LDR increases; current in LDR decreases
  • Dresistance of LDR increases; current in LDR increases
