🔍 Key Concepts

• Relationship between inductors in parallel and resistors in parallel in basic DC circuits • Formula for equivalent inductance when two inductors are connected in parallel with no mutual coupling • Difference between series and parallel combinations of inductance

💭 Think About

• Ask yourself: when two similar components are placed in parallel (like resistors), does the total value become larger than the largest, smaller than the smallest, or somewhere in between? • Think about how current divides between parallel branches—what does that do to the total inductance seen by the source? • Compare the known formula for resistors in parallel to what you would expect for inductors in parallel without coupling.

✅ Before You Answer

• Verify whether series combination of inductances is the one where you add the values directly • Check if the correct expression for equivalent inductance of two inductors in parallel is of the product-over-sum form • Confirm that the total inductance in parallel should not be larger than both individual inductances
