    I found this measage in my inbox. I do not reply on PM questions, specialy those who ask to send the answer to email.
    This is an open forum, so I posted it where it should be.

    HI please I need some help with the folwing example as I dont understand it at all I tryed the inter net but again it's not easy for me to understand it
    Please copy your answer to my hotmail email address

    Half wave rectifire circut
    1. Carry out a transient simulation of the circuit using the default parameters.
    Investigate the effects of varying the reservoir capacitor from its initial small (1uF) value
    up to a value of 1000uF in suitable steps. Plot the results.
    Also investigate the effect of varying the load value (set by R1).
    Plot and sketch the values of the diode current as the load resistor is varied.
    Comment on the following:-
    1. What sets the value of the peak DC output voltage given that the mains is a constant
    230VAC rms.
    2. What causes the difference between the peak secondary voltage and the peak output
    voltage with no reservoir capacitor
    3. What is the relationship between the droop on the output between peaks and the
    values of the reservoir capacitor and the load resistance.
    4. Why is the diode current waveform not a sine wave?

    Here are som circuits with diodes, including the various rectifiers.

    How to put pictures on this forum is explained in the FAQ.

    How do I attach a file to a post?
    To attach a file to your post, you need to be using the main 'New Post' or 'New Thread' page and not 'Quick Reply'. To use the main 'New Post' page, click the 'Post Reply' button in the relevant thread.
    On this page, below the message box, you will find a button labelled 'Manage Attachments'. Clicking this button will open a new window for uploading attachments. You can upload an attachment either from your computer or from another URL by using the appropriate box on this page. Alternatively you can click the Attachment Icon to open this page.
    To upload a file from your computer, click the 'Browse' button and locate the file. To upload a file from another URL, enter the full URL for the file in the second box on this page. Once you have completed one of the boxes, click 'Upload'.
    Once the upload is completed the file name will appear below the input boxes in this window. You can then close the window to return to the new post screen.
    What files types can I use? How large can attachments be?
    In the attachment window you will find a list of the allowed file types and their maximum sizes. Files that are larger than these sizes will be rejected. There may also be an overall quota limit to the number of attachments you can post to the board.
    How do I add an image to a post?
    If you have uploaded an image as an attachment, you can click the arrow next to the 'Attachment Icon' and select it from the list. This will be inserted into your post and can be located where you want it displayed.
    To include an image that is not uploaded as an attachment and is located on another website, you can do so by copying the full URL to the image, (not the page on which the image is located), and either pressing the 'Insert Image' icon or by typing [​IMG] after it, ensuring that you do not have any spaces before or after the URL of the image. You can insert pictures from your albums (?) in this way too.
