Question

In each of the following questions, Match column-I and column-II and select the correct match out of the four given choices.(B) Ammeter (Q) Moderate resistance (C) Voltmeter (R) High, Low or moderate resistance (D) Avometer (S) High resistance (a) $\mathrm{A} \rightarrow \mathrm{P} ; \mathrm{B} \rightarrow \mathrm{Q} ; \mathrm{C} \rightarrow \mathrm{R} ; \mathrm{D} \rightarrow \mathrm{S}$ (b) $\mathrm{A} \rightarrow \mathrm{P} ; \mathrm{B} \rightarrow \mathrm{Q} ; \mathrm{C} \rightarrow \mathrm{S} ; \mathrm{D} \rightarrow \mathrm{R}$ (c) $\mathrm{A} \rightarrow \mathrm{Q} ; \mathrm{B} \rightarrow \mathrm{P} ; \mathrm{C} \rightarrow \mathrm{R} ; \mathrm{D} \rightarrow \mathrm{S}$ (d) $\mathrm{A} \rightarrow \mathrm{Q} ; \mathrm{B} \rightarrow \mathrm{P} ; \mathrm{C} \rightarrow \mathrm{S} ; \mathrm{D} \rightarrow \mathrm{R}$

Short answer

The short answer is: The correct match is \(A \rightarrow Q; B \rightarrow S; C \rightarrow R\), which corresponds to option (d).

Step-by-step solution

Identify the characteristics of Ammeter

: An ammeter is a device used to measure the electric current in a circuit. It has a moderate resistance to allow the current to flow through it.

Identify the characteristics of Voltmeter

: A voltmeter is a device used to measure the potential difference between two points in a circuit. It has a high resistance to minimize the current flow through it, thus ensuring accurate voltage measurements.

Identify the characteristics of Ammeter, Voltmeter, and Ohmmeter

: An Avometer is a combination of an ammeter, voltmeter, and ohmmeter. It can measure current, voltage, and resistance in a circuit. Depending on the application, it may have high, low, or moderate resistance.

Match the instruments with their characteristics

: From our analysis: - A(Ammeter) matches with Q(Moderate resistance) - B(Voltmeter) matches with S(High resistance) - C(Avometer) matches with R(High, Low, or moderate resistance) Therefore, the correct match is \(A \rightarrow Q; B \rightarrow S; C \rightarrow R\), which corresponds to option (d).
