A circuit to verify Ohm's law uses ammeter and voltmeter in series or parallel connected correctly to the resistor. In the circuit :
Open in App
Solution
The correct option is C ammeter is always connected in series and voltmeter in parallel
Assuming a circuit has one resistor which is used for the verification of Ohm's law.
Here, we have one ammeter and one voltmeter which will be connected to this circuit.
If we consider this circuit then, a current will pass through this resistor. So the current will be same in whole circuit as this resistor is connected in series.
The ammeter is used for measuring the current, so it will be connected to circuit in series.
The voltmeter measures voltage change between two points in a circuit, so it will be connected in parallel with resistor
Hence, option (C) is correct.
