Слайд 2 Problem 13.9 Find Vx in the network shown.

Слайд 3 Problem 13.21 Find I1 and I2 in the circuit. 13.90. Calculate

the power absorbed by the 4-Ω resistor.
Слайд 4 Problem 13.22 Find current Io in the circuit.
With more complex mutually

coupled circuits, it may be easier to show the effects of the coupling as sources in terms of currents that enter or leave the dot side of the coil. The Figure then becomes,
Слайд 5 Problem 13.22 Find current Io in the circuit.

Слайд 6 Problem 13.28 find the value of X that will give maximum

power transfer to the 20-Ω load.
