In order to determine the correct comparison between the voltmeter and ammeter readings in circuits P and Q, we would need additional information about the configurations of circuits P and Q, such as their resistances, power sources, and whether they are in series or parallel.
However, I can help explain the general relationships for voltmeters and ammeters:
1. A voltmeter measures the potential difference across two points in a circuit and is connected in parallel.
2. An ammeter measures the current flowing through a particular point in a circuit and is connected in series.
If Circuit P and Circuit Q have different resistances or configurations, the readings of the voltmeter and ammeter could vary significantly.
Given the options:
A. If circuit P has the same voltage as circuit Q but the ammeter reading in circuit P is less than in circuit Q, it might suggest that circuit P has higher resistance.
B. If circuit P has a lower voltmeter reading but the current readings are the same, it might suggest that circuit P has a higher resistance, resulting in lower voltage due to a voltage drop.
C. If circuit P has a higher voltage but a lower ammeter reading, it suggests that circuit P may have a higher resistance.
D. If circuit P has a higher voltage and a higher ammeter reading, it implies that circuit P is likely allowing more current due to lower overall resistance.
Without further details about circuits P and Q, it's hard to choose an option definitively. Please provide more context or information about the circuits for a precise answer!
