A voltmeter and an ammeter are connected...

A voltmeter and an ammeter are connected in series to an ideal cell of `emf E`. The voltmeter reading is `V`, and the ammeter readings is `I`. Then
(i) `V lt E` (ii) the voltmeter resistance is `V// I`
(iii) the potential difference across the ammeter is `E - V`
(iv) Voltmeter resistance + ammeter resistance = E//I`
Correct statements are

A

`I and ii`

B

`ii and iii`

C

`iii and iv`

D

all

Text Solution

Verified by Experts

The correct Answer is:
A, B, C, D
Treat all voltmeters and ammeters as resistances. Draw the circuit and find the currents and potential differences for each section.
