Verified Answer
Consider two identical galvanometers and two identical resistors with ...
The range of voltmeter ‘V’ is given by the expression
V is max in this case as RHS is maximum. Thus (a) is correct.
The range of ammeter I is given by the expression
The range of ammeter I is given by the expression
Here Req is minimum and therefore I is maximum. Thus (c) is the correct option.

Consider two identical galvanometers and two identical resistors with ...
Is negligible, and they are connected in series with the resistors as shown in the circuit diagram below:
```
+----R----+----R----+
| | |
G1 G2 |
|
===
V
===
|
|
GND
```
where G1 and G2 are the two galvanometers, V is a voltage source, and GND is ground.
Then the current through each galvanometer and resistor is the same, by Kirchhoff's current law. Let's call this current I.
The voltage across each resistor is IR, since they have the same resistance R.
The voltage across the two galvanometers must add up to the total voltage of the source V, since they are in series. Let's call the voltage across G1 V1, and the voltage across G2 V2. Then we have:
V = V1 + V2
Now, each galvanometer has a sensitivity S, which is the deflection produced per unit current. Let's assume that the galvanometers are calibrated so that their sensitivities are equal, i.e. S1 = S2 = S.
Then the deflection produced by each galvanometer is proportional to the voltage across it, by Ohm's law. We can write:
deflection of G1 = S * V1
deflection of G2 = S * V2
Substituting V = V1 + V2, we get:
deflection of G1 = S * (V - V2)
deflection of G2 = S * V2
Now, suppose we reverse the connections of G2, so that it is now connected in parallel with G1, as shown in the circuit diagram below:
```
+----R----+
| |
G1 |
G2
| |
+---------+

===
V

|

GND
```
Then the voltage across each galvanometer is the same, by Kirchhoff's voltage law. Let's call this voltage V'.
The current through each galvanometer and resistor is now different, since they are in parallel. Let's call the current through G1 I1, and the current through G2 I2. Then we have:
I1 = V' / R
I2 = V' / (R + RC)
The deflection produced by each galvanometer is still proportional to the voltage across it, by Ohm's law. We can write:
deflection of G1 = S * V'
deflection of G2 = S * V'
Now, suppose we want to compare the deflection of G1 in the two circuits, i.e. when G2 is in series and when G2 is in parallel. We can do this by comparing the ratio of the deflections.
Ratio of deflections = deflection of G1 with G2 in series / deflection of G1 with G2 in parallel
= (S * (V - V2)) / (S * V')
= (V - V2) / V'
Substituting V' = V / (1 + RC/R), we get:
Ratio of deflections = (1 - V2/V) / (1 + RC/R)
Now, suppose we want to compare the deflection
```

where G1 and G2 are the two galvanometers, V is a voltage source, and GND is ground.

deflection of G2 = S * V2
Substituting V = V1 + V2, we get:
deflection of G1 = S * (V - V2)
deflection of G2 = S * V2
Now, suppose we reverse the connections of G2, so that it is now connected in parallel with G1, as shown in the circuit diagram below:

The current through each galvanometer and resistor is now different, since they are in parallel. Let's call the current through G1 I1, and the current through G2 I2. Then we have:
I1 = V' / R
I2 = V' / (R + RC)
The deflection produced by each galvanometer is still proportional to the voltage across it, by Ohm's law. We can write:
deflection of G1 = S * V'
deflection of G2 = S * V'
Now, suppose we want to compare the deflection of G1 in the two circuits, i.e. when G2 is in series and when G2 is in parallel. We can do this by comparing the ratio of the deflections.
Ratio of deflections = deflection of G1 with G2 in series / deflection of G1 with G2 in parallel
= (S * (V - V2)) / (S * V')
= (V - V2) / V'
Substituting V' = V / (1 + RC/R), we get:
Ratio of deflections = (1 - V2/V) / (1 + RC/R)
Now, suppose we want to compare the deflection
