    hey guys for an I-V converter will the the 2 waveforms be in phase??
    i mean if the current and voltage originally are in phase will this voltage converted to current and the original voltage waveform be in phase same as original one or an time delay will be introduced

    If the I-V converter is a resistor, the V output will be in phase.

    well it's not just working... i tried to simulate a circuit wid phase shift of degrees cro being connected across the resistor and other channel across the resistor... as they have same ground it's not just working... i desire to get separate waveforms for voltage and current

    Can you share your circuit?

    First you have to type better, then I can gather this:
    You want to check a phase shift on a waveform.
    You want to make a circuit to see the differences in the scope.
    Well you will need an AC source and a current probe for the oscilloscope to see the I-V.

    well thanx... u r spot on...
    well how do i see the phase shift practically...
    i mean i want to build a circuit which will have 2 points one for the original voltage to be displayed on the scope and one for the current which is converted into the voltage waveform....

    No fisrt you need an AC source then you need an oscilloscope then you need a current probe for the oscilloscope then you can insert a capacitor o an inductor in series and you should see the phase shift of the waveforms on each scope channel.

    but why should i insert any element to see the waveform shift if i'm giving the ohase shift from the source itsef

    As Thingmaker said, if you want a coherent answer, post a schematic of what you want to measure, and how you are trying to do it.
