The self inductance of two coils are 4mH and 9mH respectively. If the coefficient of coupling is 0.5, the mutual inductance between the coils is _____
The total inductance of two coupled coils in the ‘series aiding’ and ‘series opposing’ connections are 1.4 × 10^{3} Henry and 0.6 × 10^{3} Henry, respectively. The value of mutual inductance will be:
An aircore radiofrequency transformer as shown has a primary winding and a secondary winding. The mutual inductance M between the windings of the transformer is ______ μH.
(Round off to 2 decimal places.)
Determine the mutual inductance between two coils when a current changing at 20 A/s in one coil induces an EMF of 50 mV in the other.
Two inductive coils which are close to each other have a mutual inductance of 0.3 H. Current through one coil is increased from 1 A to 4 A in 0.03 s. The voltage induced in the other coil is:
Two coupled coils have self inductances L_{1} = 10 mH and L_{2} = 20 mH.
