A voltmeter of resistance `200 Omega` is used to measure `p.d` across resistances `100 Omega` and `200 Omega`.
.

Options

A. The voltmeter reads `1 V`, when connected across `100 Omega`
B. The voltmeter reads `2 V`, when connected across `200 Omega`
C. Both (1) and (2)
D. None

Answer

C

Explanation

`V_1 = (200//3)/(200 + (200)/(3)) xx 4`
`= 1 V`

`V_2 = 2 V`.
