A circuit to verify Ohm's law uses ammeter and voltmeter in series or parallel connected correctly to the resistor. In the circuit:
Option 1 -
Ammeter is always used in parallel and voltmeter is series.
Option 2 -
Both ammeter and voltmeter must be connected in parallel.
Option 3 -
Ammeter is always connected in series and voltmeter in parallel
Option 4 -
Both, ammeter and voltmeter must be connected in series
-
1 Answer
-
Correct Option - 3
Detailed Solution:In Ohm's law experiment, ammeter is used in series because in series same current will flow through it. But voltmeter is used in parallel to resistor to measure the potential difference across it.
