Answer following questions: (a) At t = 5 ms, a sinusoidal current i is known to be zero and going negative. The current is next zero att = 25 ms. It is also known that the current is 50 mA at t = 0. • What is the linear frequency of the current i • Find an expression for i(t) (b) Two voltage sources given as vi = 10cos(100rt+20°)V and v2 = only sources of a given electric circuit. A resistor R is a component in this circuit and carries current i. When v2 is short circuited peak current through R is 2 A and current is leading v1 by 40°. When vị is short circuited peak current through R is 3 A and current is lagging v2 by 10°. Find a suitable expression for i(t) 20sin(300nt – 40°)V are the
