38.
In measuring a resistance by voltmeter-ammeter method, the voltmeter can be connected either across supply or across the resistance. If the resistance is low, the voltmeters should be connected
across the supply
across the resistance
either in two positions
preferably across the supply
Answer: Option
Explanation:

Since resistance is low current is high and voltage drop across ammeter is high. Therefore, voltmeter should be connected across resistance.
