This simulation show this objective 8) "Computer simulations, or demonstrations using a cathode-ray oscilloscope, are powerful methods of demonstrating alternating currents {( deduce that the mean power in a resistive load is half the maximum power for a sinusoidal alternating current), ( represent a sinusoidally alternating current or voltage by an equation of the form x = x_osin?t), is it? Correct? ???Thank you very much
