Physics
In the circuit given below, identify the correct relation between the currents flowing through the 2 Ω, 3 Ω, and 5 Ω resistors:
- current through 2Ω > current through 3Ω
- current through 5Ω < current through 3Ω
- current through 2Ω = current through 5Ω
- current through 5Ω > current through 3Ω
Answer
current through 2Ω = current through 5Ω
Reason —
Given,
Emf of the cell (ε) = 12 V
As, same current flows through 3 Ω and 2 Ω resistances so they are connected in series and their net resistance will be :
RS = 2 + 3 = 5 Ω
Since, RS and 5 Ω have same potential difference so they are in parallel combination.
As resistance in both the arms is the same (5 Ω) so equal current flows through (3 Ω + 2 Ω) combination and 5 Ω.
Hence, current through 2Ω = current through 5Ω.
