How to Measure Current Flow
Current flow is a term used to describe the action of electrical current. When there is current flow, an electrical device is consuming electrical power, which is a product of voltage and current. There is no current flow unless there is an... Read More »

How Electrical Current Flows
Personal danger from electricity comes from current flowing through you. Electricity seeks the path of least resistance from an area of higher concentration to an area of lower concentration. Some materials, called conductors, carry a charg... Read More »

How to Build a Current Flow Sensor
Sensing current flow involves using Ohm's Law: Voltage = Current x Resistance. This article will show how to make a current flow sensor which will trip an alarm when current at or above a threshold limit is reached. This is a simple way to ... Read More »

Real current refers to an analysis of the charges that actually flow - for example electrons in a metal - as opposed to the "conventional current", that uses a ficticious current of positive charges. If the electrons move to the left, the "...

It will flow if there is a voltage. Basically, that implies there is an electric field that attracts or repels charged particles.

For metallic conductors, current is a drift of free electrons from negative to positive (although we often describe it as 'conventional flow', from positive to negative!). In liquids and gases, though, this may not be the case, as current c...
