Transcript of Inductors

Inductors
Like resistors with restistance and capacitors with capacitance, an inductor has inductance.
Inductance is a measure of how much magnetic flux goes through a loop for the current supplied.
Yet it is purely a geometric quantity and is solved from:
Unit: Henry,
Like resistance and capacitance, it is used to find other quantites in a circuit.
Energy
What is the inductance of a loop of 30 wires having a radius of .5 cm, and a length of .125 cm?
If it takes 3 ms to reach a current of 2.5 A through this inductor, what potenial is built up across it?
Now that the current is built up, what energy is stored in this inductor?
