plz tell me dat why current is unchanged in phase and only voltage gives phase reversal after reflection frm an an infinite transmission line???????????
why current is not reversed in phase?????????
why current is not reversed in phase?????????
Indeed - an infinite line has no reflections, since the incident wave never meets a discontinuity to reflect from.In an INFINITE transmission line:
What does voltage have to do with phase reversal?
What does current have to do with phase reversal?
There is no reflection in an infinite line. Thats why it is unchanged.an infinite line has no reflections
Well - consider what happens at an open circuit connected to a source. There is voltage (potential difference) across the open circuit but no current flow. From the perspective of a travelling wave on a transmission line, how do we account for the zero current condition in the open circuit at the end of the line? The incident current wave coming from the source must be exactly cancelled by a reflected wave travelling back to the source. The only way for the two current waves to cancel is for them to have equal magnitude and to be in anti-phase, or 180° out of phase.if we are counting up electons only so why reflection of current takes place in pen circuited transmission line and voltage is unchanged?
