Calculate Inductor energy: 500uH, 6A, J


Energy stored in an inductor. You can calculate the energy knowing the inductance and the current through the inductor. You can also calculate the inductance necessary to store a desired amount of energy at a given current, or the current at which a given inductance stores the desired amount of energy.   E = ½ L.I2   formula.

Enter any 2 values, the 3rd field will be calculated:

Inductor energy formula says:

•A 500uH (five hundred microhenrys) inductor at 6A (six amperes) stores 9mJ (nine millijoules) of energy.
•To store 9mJ (nine millijoules) of energy in a inductor at 6A (six amperes), its inductance has to be 500uH (five hundred microhenrys).
•If a 500uH (five hundred microhenrys) inductor had to store 9mJ (nine millijoules) of energy, its current would have to be 6A (six amperes).
