The circuit shown in Figure P3.72 has i L ( t )= 0.1 cos( 5000t ) A in which the argumentof the cos function is in radians. Find v(t), i C ( t ), i(t), the energy stored in the capacitance, theenergy stored in the inductance, and the total stored energy. Show that the total stored energy is constant with time. Comment on the results.
A 0.1-μF capacitor has a parasitic series resistance of 10 Ω, as shown in Figure P3.39.Suppose that the voltage across the capacitance is v c ( t )=10 cos( 100t ); find the voltageacross the resistance. In this situation, to find the total voltage v( t )= v r ( t )+ v c ( t ) to within 1percent accuracy, is it necessary to include the parasitic resistance? Repeat if v c ( t )=0.1 cos(10 7 t ).
The mutually coupled inductances in Figure P3.74 have L 1 =1 H, L 2 =2 H, and M= 1 H. Furthermore, i 1 ( t )=sin( 10t ) and i 2 ( t )= 0.5 sin( 10t ). Find expressions for v 1 ( t ) and v 2 ( t). The arguments of the sine functions are in radians.
