Answer 1

The values of resistances marked on the two coils Ri and R, are found to be correct. A student connects the given resistors in the following manner :

• From given figure it is clear that, the resistors are connected in series.
• Because, one end of the resistor R1 is connected to X and the other end is connected to resistor R2.
• Similarly,
• one end of the resistor R2 is connected to Y and the other end is connected to resistor R1.
• They together completes a circle.
• Hence they are in series.
• Now, the resistance is given by,
• Rs = R1 +R2
• = 3 + 6
• ∴ Rs = 9 ohm
