An ammeter has a current range of 0-5 A, and its internal resistance is 0.2 Ω. In order to change the range to 0-25 A, we need to add a resistance of
1
0.8 Ω in series with the meter
2
1.0 Ω in series with the meter
3
0.04 Ω in parallel with the meter
4
0.05 Ω in parallel with the meter
5
none of these
