railway DFCCIL Junior Executive 2023 (CBT 1 & CBT 2) Mock Test Electrical and Electronics Measurements Extension Ranges of Basic Meters
How will you extend the range of measurement in case of an ammeter and voltmeter?
1
Shunt a resistance across voltmeter and inductance in series with the ammeter
2
Shunt a resistance across the ammeter and capacitance with zero resistance in series with the voltmeter
3
Shunt a resistance across the ammeter and inductance in series with the voltmeter
4
Shunt a resistance across the ammeter and high non-inductive resistance in series with the voltmeter
