Which d orbitals of sulphur take part in the pi bonds of SO3?

is current density property of a material j⃗ (t,x⃗ )=ρ(t,x⃗ )v⃗ (t,x⃗ ). where ρ is charge density as a function of time and position and v is drift velocity of electrons as a function of time and position, in a conductor maintained at constant potential difference ?? is it that only having defined current density we can define current ??

What if L is varying ? varying L will vary q Actually i want to ask I=dq/dt? so, for every charge leaving the cross-section of the conductor, an equivalent one will enter. This means that across the cross-section dq/dt, the summed change of charge with respect to time, equals 0!

i am not understanding what you are trying to say can you please define current in light of my doubt this doubt pinching me since long without having cleared this i cannot proceed please help me

you mean to say in q = neAL nis causing variation in q ?? AND what if A (area of cross section) is also varying ??

i = dq/dt so for a conductor of length L, maintained at constant potential difference, we know that q = enAL where e is charge on electron n is electrons per unit vol. A is area of cross section of conductor SO in q = enAL what is changing with time so that we come across rate of change of charge
