How to find the width of a pcb track for a required voltage drop

[Murugesh_89]

Hi,
If i give 12V for a pcb and current passing through it is 5A. This board in turn supplies voltage for some other pcbs. The distance between two end pcb is 2 meters. How much width should i give for a supply voltage track so that the voltage drop is 0.5V between the two end pcbs.



Thanks,
Murugesh

It all depends on how long the trace is and what thickness copper you are using.

This should help:https://www.circuitcalculator.com/wordpress/2006/01/31/pcb-trace-width-calculator/

Well thanks barry.

Here, if i give current, thickness and length as inputs it will give the output for voltage drop and width.

In addition i want to find the width of track if i give required voltage drop as input or vice versa. Is there any other tool available?


Thanks,
Murugesh
