How can you increase the energy stored in an inductor by times?
Step 1: Given data and assumptions.
Self-inductance of the inductor
Energy stored in the inductor
Let the current passing through the inductor be .
Step 2: Find the energy stored in the inductor.
We know that,
The energy stored in an inductor is given as:
Where,
is the stored energy in the inductor.
is self-inductance of the inductor.
is the current passing through the inductor.
Since,
Therefore, the energy stored in an inductor is directly proportional to the current passing through the inductor.
If the current is doubled, the energy stored in the inductor will become times.
Hence, the energy stored in an inductor increased by times when the current is doubled.
