In the given circuit diagram, two resistance wires A and B are of same area of cross-section and same material, but A is longer than B. Which ammeter A1 or A2 will indicate higher reading for current? Give reason. |
|
Answer» Ammeter ,A2 shows a higher reading. Since wire ,A1 is longer, it has greater resistance and so draws lesser current. So more current flows through B and ,A2 shows a higher reading. |
