An electric current is simply the movement of charged particles. These particles are usually electrons. Electric current is measured by amperes.

∙ 15y agoAt its most basic level, just the electrons that can be coaxed from their positions in the valence bands of atoms. Some of the measurements we make are things like energy potential (voltage), charge flow (current) and resistance to the flow of charges. Then there is the math we can do with this information: power equations, phase difference between capacitance and inductance, "tuning" a circuit for power, node equations, heat dissipation, Norton and Thevanin equivalence, scads of calculus... Then there is the chemistry of batteries, whether a material makes a good conductor or insulator, or semiconductor (a whole different animal), the effect of current on biological stratum and vice-versa (bioelectronics)... and the really cool stuff when you get into plasmas where all the electrons get stripped from the atoms (oops, now I'm salivating again)...

When a switch in an electrical circuit is turned off what will happen?
Closing a switch in an electrical circuit will complete the circuit. The supply voltage will then be applied to that circuit, and current will flow through that circuit.
Where is the store of electrical energy in a circuit?
Capacitors, inductors, and batteries all store electrical energy.
What is a single route for electrical current called?
A single route for electrical current is called a branch circuit.
What statements is not correct about the elements in a circuit?
a switch is rarely used in electrical circuits
How do you show on a circuit diagram that the output on an electrical device can be varied?
45353415343 434 413
What has a simple circuit?
A simple electrical circuit consist in a source of power (like a battery), a conductor (like a wire), and a load (like a light bulb, a motor, a resistor, etc)
What is electrical panel and PLC panel?
Electrical panel consist of hardwired circuits, a plc is a panel that uses logic like a computer and it's progrmamable to have a circuit switch on or off
When you turn on a television what is the electrical circuit?
The electrical circuit when turned on it is considered closed. By the same token when an electrical circuit is turned off the electrical circuit is considered open.
What things need a electrical circuit?
Electrical devices need an electrical circuit.
What type of energy flows in a circuit?
Quite often, the word "circuit" is used for an electrical circuit. In that case, the energy is electrical energy.
The drawing of an electrical circuit is called?
The drawing of an electrical circuit is called a.............= schematic drawing.
Does blu-tack break an electrical circuit?
No, an electrical approved switch is used to break an electrical circuit.
When a switch in an electrical circuit is turned off what will happen?
Closing a switch in an electrical circuit will complete the circuit. The supply voltage will then be applied to that circuit, and current will flow through that circuit.
Internal circuit of an electrical relay?
basic circuit of electrical protective relay
What is the only thing that can use power in an electrical circuit?
The load that is connected to the circuit is what draws the power of the electrical circuit.
What is the function of a cell in an electrical circuit?
it's function is to supply energy(electric)
What do you call the path electricity takes?
The electrical path is termed an electrical circuit.
