Question

What do \[L_1\] and \[L_2\] represent in \[M=K\sqrt{L_1L_2}\] ?

Options

• Self-inductances of coil 1 and coil 2

• Lengths of coil 1 and coil 2

• Currents in coil 1 and coil 2

• Magnetic fluxes through coil 1 and coil 2

Answer 1

The symbols \[L_1\] and \[L_2\] denote the self-inductances of coil 1 and coil 2. Together with \[K\] , they determine the mutual inductance.
