guys can you help in solving this problems 1.a pure inductance o L=0.01 Henry passes a current i=5cos2000t.What is the voltage across the element. 2. In a series of R=5Ω and L=0.06 Henrys the voltage across the inductance is VL=15sin200T volts .Fnd the rtotal voltage ,the current'the angle by which i lags Vsub t and the magnitude of the impedance. 3.A series circuit by two pure elements has the following applied voltage and resulting current. vt=150cos(200t-30) volts i=4.48 cos (200t-56.6)A. find the elements comprising the circuit
