A circuit is shown below.

A

If `A` is an ideal ammeter, B an ideal battery of voltage `V`, and `C` an ideal voltmeter, the ratio reading of `C//` reading of `A` is `R. `

B

If A is a capacitor, B an ideal ammeter and C an ideal battery of voltage V, the potential difference across the capacitor is zero.

C

If A is an ideal ammeter, B an ideal battery of voltage of V, and C an ideal voltmeter, the ratio reading of `C//`reading of A is` R//2`

D

If A is a capacitor, B an ideal ammeter, and C an ideal battery of voltage V, the potential difference across the capacitor is 2 V.

Text Solution

Verified by Experts

The correct Answer is:
A, B
a.,b.
Reading of C = V {i in that branch = 0}
Reading of `A = V/R rArr R`
`V_(B) = I R_(ammeter) = 0 rArr V_(cap) =0` .
