Practicing Success
You are given two wires A and B with diameter 2 cm and 5 cm respectively. Both of these wires are connected to batteries of same voltage. In which wire the current flowing will be greater? |
Wire A Wire B The current will be the same. Cannot be predicted. |
Wire B |
In wire B, the area of cross section will be greater, hence, the current flowing through it will be higher. I = neAvd |
