Homework Help: Current (y-axis) against time (x-axis) graph -- help please

  1. Nov 30, 2014 #1
    Please, can someone give me some help?

    The question is:

    Draw a graph of current (y-axis) against time (x-axis) to illustrate exactly what is meant by an alternating current of 50 Hz and peak value 12 V?

    My attempt:

    Look for help on-line. Google 'plotting graphs', or something similar. Alternatively, consult your textbook, if you have one.

    The point is that trying to explain how to plot graphs in a PF message is impractical; all the explanations and details have already been written up by others, and the explanations are readily available.

    Are you sure you have the correct assignment? Your OP mentions plotting current against time, and then you mention an alternating current of 50 Hz with a peak value of 12 V. Volts are not used to measure current, which is supposed to be measured in units of amperes.
