A wire Carrying Current is?A good conductor while carrying current is
- negatively charged
- positively charged
- electrically charged
- alternately charged positive and negative
The SI unit for measuring an electric current is the ampere, which is the flow of electric charge across a surface at the rate of one coulomb per second. Electric current is measured using a device called an ammeter.
Electric currents cause Joule heating, which creates light in incandescent light bulbs. They also create magnetic fields, which are used in motors, inductors and generators.
The moving charged particles in an electric current are called charge carriers. In metals, one or more electrons from each atom are loosely bound to the atom and can move freely about within the metal. These conduction electrons are the charge carriers in metal conductors.
A good conductor while carrying current is negatively charged.
