Question

A circuit to verify Ohm's law uses ammeter and voltmeter in series or parallel connected correctly to the resistor. In the circuit :

• A. ammeter is always connected series and voltmeter in parallel.
• B. Both, ammeter and voltmeter mast be connected in series.
• C. Both ammeter and voltmeter must be connected in parallel.
• D. ammeter is always used in parallel and voltmeter is series.

Answer 1

Answer: (A)

Conceptual
Option (1) is correct
Ammeter :- In series connection, the same current flows through all the components. It aims at measuring the curent flowing through the circuit and hence, it is connected in series.
Voltmeter :- A voltmeter measures voltage change between two points in a circuit, So we have to place the voltmeter in parallal with the circuit component.
