Question 33
H

A circuit contains an LDR joined end to end with a fixed resistor across a cell. The circuit is moved from a bright room into a dark cupboard. What happens to the resistance of the LDR and to the current?

[1]
A

The resistance of the LDR falls and the current in the circuit rises

B

The resistance of the LDR falls and the current in the circuit falls

C

The resistance of the LDR rises and the current in the circuit rises

D

The resistance of the LDR rises and the current in the circuit falls
