The current in a resistor is given by I = (2.0 A) sin (380t).
(a) What is the frequency of the current?
(b) What is the rms current?
(c) How much aver-age power is delivered to the resistor?
(d) Write an equation for the voltage across the resistor as a function of time.
(e) Write an equation for the power delivered to the resistor as a function of time.
(f) Show that the rms power obtained in part (e) is the same as your answer to part (c).
