1)

The figure shows an inductor and Resistance connecdted in series across a battery of EMF=V. Choose the correct options. At time t=0,
i) Potential drop across Inductor is 0.
ii) Potential drop across Inductor is V.
iii) Potential drop across Resistance is V.
iv) Potential drop across Resistance is 0.

Shouldn't it be i,iv?

2) Assertion-Reasoning Type:-
2 bulbs - 1 of (100W,220V) & the other of (60W,220V) are connected in series across a 440V supply.

S1:- 60V bulb will get fused.
S2:- Since series connection, so V=V1+V2...here V1<220V...& V2>220V.

Shouldn't it be F,F ?

3) A coil of Inductance 100μH and 60ohm resistance is connected in parallel with a condensor of 100pF. The resosnance-circuit so formed is excited from an alternating current source. The frequency of the source is varied until the maximum impedence of the circuit is obtained. The frequency of the generator at which this happens is 10n2π. n=?
