Answer:
A) A warm wire
Explanation:
A warm wire has the most resistance. Heating the metal wire causes atoms to vibrate more, which in turn makes it more difficult for the electrons to flow, increasing resistance. Heating the wire increases resistivity.
Answer:
The time is 106.7 minute.
Explanation:
Given that,
Density
Current
Diameter of wire = 1.2 mm
Length = 31 cm
We need to calculate the drift velocity
Using formula of drift velocity
Put the value into the formula
We need to calculate the time
Using formula for time
Where, l = length
= drift velocity
Put the value into the formula
Hence, The time is 106.7 minute.
