CBSE X Physics Electricity
When a potential difference of 2v is applied across a end of a wire of 5m length, a current of 1A is found to flow it. Calculate
1. resistance per unit length
2. resistance of 2m unit length
3. resistance across ends of the wire if is doubled on itself.

- .An ELECTRIC IRON has a rating750W;220Vcalculate:
- [R] resistance
- [I] current
- why is fuse had to have lowmeltingpoint & high resistivity?
