The circuit diagram shows a light-dependent resistor (LDR) as part of a potential divider. A voltmeter is connected across the LDR. At a particular light intensity, which row gives the resistance of the LDR and the potential difference (p.d.) reading on the voltmeter?
- Alight level: bright; resistance of LDR: low; p.d. shown on the voltmeter: high
- Blight level: bright; resistance of LDR: high; p.d. shown on the voltmeter: low
- Clight level: dim; resistance of LDR: high; p.d. shown on the voltmeter: high
- Dlight level: dim; resistance of LDR: low; p.d. shown on the voltmeter: low
