An emf 0.55V is induced in an inductor when the current through it changes from 3.5A to 0A in 0.45s. What is it’s inductance?
✅ Answers
Answerer 1
L=E delta t/delta I
Answerer 2
The inductance is 71 mH.
Derivation:
Voltage = Inductance * (Change in Current)/(Change in Time)
0.55 V = L * (3.5 A)/(0.45 s)
0.55 V = L * 7.8 A/s
L = 0.071 H
