railway RRB Technician Grade 1 Mock Test 2024 Physics Current, Resistance and Electricity Combination of Resistors — Series and Parallel
A wire of length ‘l’ and resistance 100 Ω is divided into 10 equal parts. The first 5 parts are connected in series while the next 5 parts are connected in parallel. The two combinations are again connected in series. The resistance of this final combination is:
1
26 Ω
2
52 Ω
3
55 Ω
4
60 Ω
