Question

Choose the correct alternative which matches the second and third columns with the first column.

• A. $\left(I\right)-\left(b\right)-\left(ii\right);\left(II\right)-\left(c\right)-\left(iv\right);\left(III\right)-\left(a\right)-\left(i\right);\left(IV\right)-\left(d\right)-\left(iii\right)$
• B. $\left(I\right)-\left(a\right)-\left(i\right);\left(II\right)-\left(b\right)-\left(iii\right);\left(III\right)-\left(c\right)-\left(iv\right);\left(IV\right)-\left(d\right)-\left(ii\right)$
• C. $\left(I\right)-\left(d\right)-\left(iii\right);\left(II\right)-\left(b\right)-\left(iv\right);\left(III\right)-\left(a\right)-\left(i\right);\left(IV\right)-\left(c\right)-\left(ii\right)$
• D. $\left(I\right)-\left(C\right)-\left(iv\right);\left(II\right)-\left(a\right)-\left(ii\right);\left(III\right)-\left(d\right)-\left(i\right);\left(IV\right)-\left(b\right)-\left(iii\right)$

Answer 1

The correct option is D $\left(I\right)-\left(C\right)-\left(iv\right);\left(II\right)-\left(a\right)-\left(ii\right);\left(III\right)-\left(d\right)-\left(i\right);\left(IV\right)-\left(b\right)-\left(iii\right)$

(I) : A tap key is represented by the symbol (c) given in column II which is used to keep the circuit open.

(II) : An ammeter is represented by the symbol (a) given in column II and is connected in parallel to the circuit.

(III) : A voltmeter is represented by the symbol (d) given in column II and is connected in series to the circuit.

(IV) : A galvanometer is represented by the symbol (b) given in column II which is connected to the circuit to detect current.
