Answer:
The time is 0.5 sec.
Explanation:
Given that,
Voltage V= 12.00 V
Inductance L= 1.20 H
Current = 3.00 A
Increases rate = 8.00 A
We need to calculate change in current
We need to calculate the time interval
Using formula of inductor
Where, = change in current
V = voltage
L = inductance
Put the value into the formula
Hence, The time is 0.5 sec.
