a) Knowing the current through a 10O resistor is given by i(t)=e^-3t A. Determine the energy delivered to the resistor between t=0 and t=8.b) If the voltage across the same resistor is found to be v(t)=10sin(2pt) V, calculate the energy delivered to the resistor between t=0 and t=2s. The argument of the sine function (2pt) is in radians.
