Electric current is simply the flow of free electrons in a conductor. It is usually defined as the rate of charge flow, because the free electrons represent an electric charge.

What is electical circuits?
It is a way in which electrons from a voltage or current source stream. Electric current stream in a shut way is called an electric circuit. The point where those electrons enter an electrical circuit is known as the source of electrons.
Why low power factor need surcharge?
Low power factor leads to higher current in the system for the same real power requirement. (Check out the power triangle in any basic electical engg. book) higher current leads to higher system losses for the supply & distribution companies, drop in voltage, also necessiates higher sizing of system components. Hence low power factor attracts penalty also on the other hand some distribution companies provides incentives for maintaining higher pf. Regards, Sameer Shaikh
Are electric baseboard heaters efficient?
Amps and Watts measure different things. An Amp is a measure of electrical current and a Watt is a measure of Power. Which ever device draws the higher amperage will be the one that uses more electricity! Hence the 240 watt heater draw less amps even though it uses more watts: Volts Watts/Electical Current Amps/Power example heater 240 volt draws 2000/1000 watts - but uses 8.3/4.2 amps example heater 120 volt draws 1500/750 watts - but uses 12.5/6.3 amps
What is phase current?
A phase current is the current passing through a phase, whereas a line current is the current flowing through a line.
Why does collector current increase with base current?
the collector current is directly proportional to the base current
What does conductivity measure?
electical current
A substance that dissolves in solution to conduct an electical current is?
An electrolyte
What is the mean by the word A'C in electical system?
AC refers to Alternating Current, as opposed to DC which is Direct Current.
What is electical conductivity?
It is a measure of an objects ability to conduct electrical current between two points
When was Majectical Electical created?
Majectical Electical was created in 2008-08.
What was the caused of the fires?
electical
What was the causes of the ballantyne's fire?
electical
Is one mega ohm less then 1 volt?
Like comparing apples and oranges. Ohms are resistance to electrical current. A megaohm is 1 million ohms. Volts are measurements of electical potential.
Is charcoal an electical conductor?
No charcoal is not an electrical conductor
Does electical energy transform into other energies?
yes
What is the energy that moves electric charges?
Electical Energy
What is the loop electricity travels in is called a?
an electical currant
