# what does negative current mean [Solved]

It is all rather arbitary.
The normal convention (from the early days.) is to consider that current flows from a positive or higher voltage (potential) to: a zero, negative or lower voltage (potential). In reality this itself is a flow of electrons in the opposite direction.
In the everyday usage it simply means a flow in the opposite direction to what has been considered as positive flow in the circuit, at the beginning of the theoretical assessment. In circuit analysis one has to make assumptions at the beginning of the analysis. If the result gives a negative current, it means the flow is in the opposite direction.

Positive and negative voltage and current refer to direction. Reverse the voltage terminals, reverse the current flow (unless, of course, there is reverse current protection such as a diode).

Current is a flow of electrons which is NEGATIVE CHARGE.

Current is a flow of electrons which is NEGATIVE CHARGE.

AC stand for alternating current. AC current can oscillate at whatever frequency (# times per second, usually expressed in Hertz, Hz) you want it to. However, the power that comes into your house oscillates at 60 in the US and 50 in Europe. This has to do with the development of electricity. They had to sync up the phases when they created it and they would do this by hooking up the two sources to lightbulbs that would flash at each peak. 50 or 60 times a second is about the maximum cycle rate visible by the human eye. Positive and negative current denote which direction electrons are flowing. Nothing will happen if you touch positive or negative current, just dont touch both at the same time.
