In the circuit diagram, a light-dependent resistor (LDR) is connected to two resistors $R_1$ and $R_2$. The potential difference (p.d.) across $R_1$ is $V_1$, while the p.d. across $R_2$ is $V_2$. The current flowing in the circuit is $I$. Which statement about this circuit is correct?
- AThe current $I$ increases when the light intensity decreases.
- BThe LDR is an ohmic conductor.
- CThe p.d. $V_2$ increases when the light intensity decreases.
- DThe ratio $\dfrac{V_1}{V_2}$ is independent of light intensity.
