In the figure frequency of the `A.C`. Source is `50//pi Hz` with `L=100 H`, `C=1 muF`, `R=10 kOmega`. When all the switches are open `V_(2)` reads `100 V`. All the voltmeters are hot wire voltmeter which read r.m.s value of voltage. Initially `S_(1)`, `S_(2)` and `S_(3)` are open.

A

At any instant voltage across `R` increases at that instant magnitude of potential differences across inductor and capacitor simultaneously increases or decreases.

B

Reading of all other voltmeters are also equal to `100V`.

C

When `S_(1)` and `S_(2)` both closed reading of `V_(4)` remains `100 V`.

D

When only `S_(1)` closed reading of `V_(4)` decreases.
