Q1.Two alternating currents i1 and i2 flow in a circuit node. The output current i is given by i1 + i2.

If i1 = 5sin( 50t + /3 ) and i2 = 6cos50t

Calculate the amplitude of i and the first time that it occurs.

Q2. The instantaneous power p, in an electric circuit, is given by p = iv, where v is voltage and i is current.

Calculate the maximum value of power in the circuit if:

v = 0.02 sin(100t)volts, and i = 0.6 sin(100t + /4)amps

Also calculate the first time that the power reaches a maximum value.
