Hello Everyone,

I have the doubt about the power lines which means that if we use the wide power lines in the PCB layout what is the impedence?
I mean that low-impedence or high-impedence?
Please give me the clear explanation about this topic...
 

Wide power lines are giving low impedance
epecially ground needs to be very wide its not only low impedance path but gives EMI redcution
 

The larger the path the more electrons can flow I.E. more current... This means the path has a low-impedance...
