- When the electromotive force is removed from a circuit Containing inductance and resistance but no capacitors, the rate of decrease of the current is proportional to the current. If the initial current is 30 amp and it's down to 1 amp after 0.01 sec, what is the current after 0.03 sec?arrow_forwardThe current and voltage across a circuit element are given by the equations I(t) = 20e 100t (mA), V(t) = 105e-1⁰⁰t (V) Determine the total energy E dissipated by the element between t=0 and t=10ms. 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_forwardFind the outer radius of a coaxial cable whose characteristic impedance is 10Ω.

The displacement for all combinations of times and angular frequencies needs to be calculated. Use meshgrid.
