The instantaneous power dissipated by the element is P(t) = 1(t)V (t). Find the total energy E by integrating P(t) over the time interval from t=0 to t=10ms=0.01sec. To do so, use the function trapez(fn, a, b, h), which implements the trapezoidal rule for numerical integration and where fn is a function handle to a function that needs to be integrated, a and b are the integral limits and h is the step length. Write in Matlab the function that needs to be integrated and call function trapez with appropriate parameters.arrow_forwardQ1:lf capacitance between two conductors of a 3-phase line is 8 µF, then * capacitance of each conductorto neutral is UF 4arrow_forward
