Electric Current Definition: Electric current is defined as the flow of charged particles—such as electrons or ions—through a conductor or space. Electric Current Formula: The flow rate of electric charge is calculated by dividing the change in charge by the change in time. Electric Current Uni...
Electric current refers to the flow of electricity in an electronic circuit, and to the amount of electricity flowing through a circuit. It is measured in amperes (A). The larger the value in amperes, the more electricity is flowing in the circuit. Electricity is easy to visualize if you ...
Electric current is themovementof electric charge.It’s not the charge itself. As a metaphor, you can think of a river. If a lot of water moves past a point in the river, it means the current is strong. If the water stands almost still, it means the current is weak. (And if ther...
Electric current definition: An electric current is a flow of electric charge in a circuit. More specifically, the electric current is the rate of charge flow past a given point in an electric circuit. The charge can be negatively charged electrons or positive charge carriers including protons, ...
What is the difference between electric current and electron flow? Why are they in different directions? There is still a lot of confusion on this issue. It comes from when Benjamin Franklin first discovered electricity he thought it was positive charges that was moving along the wire. So the...
Electric current is electric charge in motion. It can take the form of a sudden discharge of static electricity, such as a lightning bolt or a spark between your finger and a ground light switch plate. More commonly, though, when we speak of electric current, we mean the more controlled ...
So, Electric current is of two types: Direct Current (DC) Alternative Current (AC) Direct Current: (DC) In this type of electric current, direction is always same. Theelectric current generatedfrom a cell orbatteryis DC. Due to the same direction of Direct Current, itsfrequencyis ZERO. In...

and the whole thing is a current-electric happening. It is an electrical phenomenon; an example of "current electricity." But no "current electricity" flows in the wires. Instead, the lighting of the bulb, the turning of the switch, the magnetic fields around the wires, and the unseen mot...
A long, vertical, metallic wire carries downward electric current. What is the direction of the magnetic field it creates at a point 2 cm horizontally east of the center of the wire? A. south B. north C. east D. west E. up
