Electro Magnetic Induction And Alternating Currents Question 486
Question: Two inductances $ L_{1} $ and $ L_{2} $ are placed closer and in parallel. Their combined inductance is
Options:
A) $ \frac{L_{1}L_{2}}{L_{1}+L_{2}} $
B) $ (L_{1}+L_{2}) $
C) $ (L_{1}+L_{2}),\frac{L_{1}}{L_{2}} $
D) $ (L_{1}+L_{2}),\frac{L_{2}}{L_{1}} $
Show Answer
Answer:
Correct Answer: A
Solution:
- Parallel $ =\frac{L_{1}L_{2}}{L_{1}\times L_{2}} $
