Calculate the correct value of resistance:
1. A wire has a resistance of \(17\ \Omega\) . Its length is doubled and its area of cross-section is reduced to half of its original value. Calculate the new resistance of the wire.
The new resistance of the wire is \(\Omega\)
[Note: Enter the answer upto one decimal places.]
2. A student states that a thick copper wire has less resistance than a thin copper wire of the same length at the same temperature.
Which of the following is the correct justification?
