3. Assume R=6.00 ohm, l=1.20m, and a uniform 2.5 T magnetic field is directed into the page. At what speed should the bar be moved to produce a current 0.50 A in the resistor?
4. A series RLC circuit has the following values: L =20mH, C=100 nF, R=20 Ohms, and the instantaneous AC voltage is given by the following expression:
v=100sin(337t(, where v is in volts and t is in sec.
Find:
a) maximum current in circuit
b)the phase angle between the current and th evoltage
c)maximum voltage across the inductor
d)resonant frequency
Also calculate the average power delivered to this RLC circuit
