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.
