The charge leaving the positive reference terminal of a voltage source is
q(t)= [6sin120pi*t - 8cos120pi*t]mC
the voltage source value is v(t)= 160cos120pi*t V.
A) Determine the power supplied by the voltage source at t=0
B) Determine the energy supplied by the voltage source during the time period between t=0 and t=1/60 s.
