How current electricity moves in a circuit?
You need a source of electrical potential difference, also known as voltage (which is the technical term for what for you call "electric pressure"). The easiest and most common voltage source is a household battery. Hook up the positive electrode of the battery using a conductor (eg. a copper wire) to one end of your circuit and the negative electrode to the other end, and voila, you'll have electric current flowing through your circuit.
Are no load and short circuit similar?
No. No load and short circuit is not similar. No load can be 1) Either open circuit i.e. Only Potential is available and load is not connected 2) Load (i.e. motor etc ) is connected but not working with full load or full capacity. In this case the current will flow through the circuit depending on the load. It means No load condition is a condition where no current or a small ( relative / comparative term) current is flowing through the circuit. In Short circuit the load side resistance/ impedance become so less that very high amount of current is passing through circuit.( The protection is therefor required for any circuit) No load and and short circuit is not similar. Thanks
Difference between electronic and electrical appliances?
The ELECTRICAL device is in which the current passes through a CONDUCTOR and the ELECTRONIC device is in which the current passes through a SEMICONDUCTOR.
Which term refers to the number of electrons that move through a conductor in one second?
That description doesn't fit any electrical term, probably because it's not useful.The number of electrons passing a single point in the conductor in one secondis proportional to the electrical current, and is described in units of amperes.
What is the the term for a semiconductor that is missing electrons?
p-type semiconductor A semiconductor that is missing electrons is called an electron hole.
Is an unbroken path through which an electric current can flow?
The term is "circuit" (from the same root as circle) An electric circuit must be uninterrupted for the current to flow. (This is why circuit-breakers are also called circuit-interruptors.)
What is the term for a material through which electrons do not readily flow?
This would likely be an "insulator" as opposed to a conductor.
What is the term for opposition to current flow within a circuit?
The term Impedance (Z) is used to quantify the opposition to current flow in a circuit.
What does a switch do in circuit?
The actual term for switch is to turn a light on and off. Another term for it is that you can put in a circuit board and when it is joined to the other side the electricity will flow through and when it is unattached the electricity will not flow through.
What current is in term of electricity?
Flow of electrons, the more there are the higher the current. Imagine water travelling through a pipe,.
What is a flow of electrons moving along a wire or conductor?
An electric current. <<>> The term used for the flow of electrons through a conductor is amperage.
What does a circuit breaker do in scientific terms?
It does what is says, breaks the circuit. The actual term for this is creating an Open. Current can only flow through a complete circuit, so if there is an open(break) in the circuit, current will not continue to run.
What is the term of the flow of electric charge?
Electric Current is the flow of electrons and hence charge
What does the term voltage and current mean?
Voltage -the rate at which energy is drawn from a source that produces a flow of electricity in a circuit; expressed in voltsCurrent - a flow of electricity through a conductor; "the current was measured in amperes"
Which term refers to the flow of electrical charges?
A flow of electrical charges is the definition of an electric current. This is a far better definition than 'a flow of free electrons', which one normally hears, because a current can be a flow of free electrons, positive or negative ions, 'holes', etc. -depending on the medium through which the current is flowing.
The pathway taken by an electric current is a?
The term is "circuit" (from the same root as circle) An electric circuit must be uninterrupted for the current to flow. (This is why circuit-breakers are also called circuit-interruptors.)
What is the term current mean?
it define electrons flow measured in ampere.
