JEE PYQ: Experimental Physics Question 14
Question 14 - 2020 (06 Sep 2020 Shift 2)
A circuit to verify Ohm’s law uses ammeter and voltmeter connected correctly to the resistor. In the circuit:
(1) ammeter is always used in parallel and voltmeter is series
(2) Both ammeter and voltmeter must be connected in parallel
(3) ammeter is always connected in series and voltmeter in parallel
(4) Both, ammeter and voltmeter must be connected in series
Show Answer
Answer: (4)
Solution
Ammeter: In series connection, the same current flows through all the components. Voltmeter: measures voltage change between two points, so it is placed in parallel.
