True orFalse?
1. The resistance of a metal rod depends on temperature.
2. The resistance of a metal rod does not depend on itsconductivity.
3. The resistance of a metal rod with fixed cross-sectional area dependson the shape of the cross sectional area.
4. A cylindrical copper rod has resistance R. It is reformed to twiceits original length with no change of volume. Its new resistance isequal to 2R.
5. Acertain wire has a resistance R. Another wire, made of the samematerial, has half the length and half the diameter of the firstwire. The resistance of the second wire is equal to R.
