# Can the value of electric current be less than 1?

Yes it can. It can actually be negative, which implies the direction of flow.

"When the circuit is solved, the circuit element currents may have positive or negative values. A negative value means that the actual direction of current through that circuit element is opposite that of the chosen reference direction. In electronic circuits it is usually assumed that all currents flow to ground. This usually matches conventional current direction, because power rail is positive in most cases."

In a setup where there are two opposite power rails and a common ground, one rail may be referred to as negative and the other positive. (This is a bit of a fiddle.) This can be effected by using a centre-tapped transformer, and feeding the power rails through diodes to give the opposite current. I did it with batteries once - I built a gadget on separate boards for the different parts (amplifier, light bank with decade counter, and electronic switching). When I decided it worked OK, I built it onto one board with one power supply. Didn't work. I had to restore the two separate lines.

On another way of looking at the question, the 'value' of an electric current can be anything from 0 upwards and depends on the units you are using. Normally amps are used, with various subdivisions like micro-amps, milliamps and so on.

Above ref, and experience

By the way, don't assume that a negative current will undo what a positive one did. If someone's dead from a DC shock, putting the current the other way round won't bring them back.
