Question 1.
What is the formula for calculating energy stored in an inductor?
Show hintHide hint
Energy depends on both inductance and current.
Question 2.
What does L stand for in the energy formula?
Show hintHide hint
It characterizes the inductor's ability.
3Question 3.
What is the formula for the energy stored in an inductor?
- E = L/I
- E = 1/2 L I²
- E = L × I²
Show hintHide hint
Notice the 1/2 factor in front of the L.
4Question 4.
True or False: An inductor can release energy immediately when it is disconnected.
- True
- False
Show hintHide hint
Consider the timing of energy release.
Question 5.
A circuit has an inductor rated at 5 H with a current of 2 A. Calculate the stored energy and discuss what would happen to this energy when the circuit is opened.
Show hintHide hint
Start with the energy formula in your calculations.
Question 6.
Predict the impact on energy storage if an inductor's inductance is doubled while the current remains constant, and explain your reasoning.
Show hintHide hint
Think about the relationships defined in the energy formula.
