31.
The equivalent unit of joule is
Answer: Option
Explanation:
Both joule and Newton-metre are units of energy.
32.
Two coils are connected in parallel. Their fluxes are adding. If the connections of one of the coils are reversed, the total inductance of the arrangement
Answer: Option
Explanation:
Mutual inductance term will become negative.
33.
The graph of a network has 6 branches with 3 tree branches. The minimum number of equations required for solution of network is
Answer: Option
Explanation:
Three tree branches mean 3 loops and hence 3 equations.
34.
In figure, S is closed at t = 0. At t = t1, I = 1 A and di/dt = 1 A/s. Then the value of L is
Answer: Option
Explanation:
i = 18(1 - e-t/L) = 6 and 
Hence L = 2H.
35.
In the circuit of figure, the switch is closed at t = 0. At t = 0+ the current supplied by battery is
Answer: Option
Explanation:
Current through an inductance cannot change instantaneously.
