SSC SSC JE Electrical 2025 Mock Test Series (Paper 1 & Paper 2) Electrical and Electronics Measurements Extension Ranges of Basic Meters
An ammeter has a range of 0 - 10 A with an internal resistance of 0.1 Ω. In order to increase its range to 0 - 30 A, we need to add a resistance of
1
0.1 Ω in shunt with the meter
2
0.05 Ω in series with the meter
3
0.1 Ω in series with the meter
4
0.05 Ω in shunt with the meter
