Question

"In the definite physical situation, the electric current flowing through the conductor is directly proportional to the potential difference applied across it". To verify this law, in which of the following circuit diagram are ammeter and voltmeter connected correctly?

• A. P
• B. R
• C. Q
• D. S

Answer 1

The correct option is D S

To verify the given law:

1. The voltmeter should be connected in parallel to the resistor and ammmeter should be connected in series with the resistor.

2. The +ve terminals of ammeter and voltmeter should be connected to the +ve terminal of the battery. Similarly, -ve terminals of ammeter and voltmeter should be connected to the -ve terminal of the battery.

So, in the (S) diagram, ammeter and voltmeter are correctly connected.
