An LDR is connected in series with a 1000 Ω resistor and a 6.0 V battery. The light shining on the LDR becomes dimmer. What happens to the potential difference across the 1000 Ω resistor?
It rises, because the resistance of the LDR falls
It rises, because the current in the circuit rises
It falls, because the current in the circuit falls
It falls, because the resistance of the LDR falls
