current is not related to nodes, it is related to branches. you can plot the current "trough" a device. the most easy thing to do is to place a 0 volt voltage source where you want to measure (say, device

Vmeas node1 node2 0

), and save the current with '`.save tran Vmeas#branch` or

.save tran i(Vmeas)

You can also add .options savecurrents in your spice netlist. It saves all the currents in the design

Thank you @User, @User,it worked.
