What do a direct electrical current is different from an alternating current because only the direct electrical current means?
In Direct Current, electrons flow from the negative pole of the electrical source, through the load, to the positive pole of the electrical source. Current is constant as there are no variations in voltage over time in the circuit. Voltage and current are measured by directly measuring the voltage and current in the circuit. In Alternating Current, electrons also flow from the negative pole of the electrical source, through the load, to the positive pole of the electrical source. However, the polarity of the poles changes +/- to -/+ to +/- , alternating polarity over and over again. This causes the direction of the electrons in the circuit to change each time the source poles change polarity. Current and voltage are not constant in an AC circuit as they vary with the waveform generated by the electrical source. In many, but not all cases, voltage and current are measured by the RMS (root-mean-square) method as directly reading the peaks of the AC waveform will not indicate the correct amount of energy in the circuit.
Can current flow in an incomplete circuit?
Maybe there's no voltage-source(AC or DC) because voltage is the one that motivates electrons to flow. It could be the connection of components in your circuit.
What is the voltage source and what is the conductor in a circuit?
The voltage source is the source of the electricity. The conductor is what the electricity flows through to reach its destination. Example: A battery is a voltage source and an electrical wire is the conductor.
What are some examples of a closed circuit?
A connection from a power source, through a load and a return back to the power source. <><><> An example: electricity is supplied to the light switch on the wall through an insulated copper wire, even though the switch is in the off position electricity is present. There is another insulated copper wire going to the light bulb. When you flip the switch the circuit is completed and the light bulb comes on.
What determines the actual magnitude and direction of current through voltage source?
The voltage itself will determine the direction of current (assuming there isn't another source pushing current through the source backwards); the amount of current will be determined by the thevenin equivalent resistance of the circuit connected to that source (the resistance "seen" by the source, which can be lumped into a single circuit element).
What is a electrical circuit?
An electrical circuit is a path which electrons from a current source flow. Electric current flows in a closed path called an electric circuit. The point where those electrons enter an electrical circuit is called the "source" of electrons. The point where the electrons leave an electrical circuit is called the "return". The exit point is called the "return" because electrons always end up at the source when they complete the path of an electrical circuit. The part of an electrical circuit that is between the electrons' starting point and the point where they return to the source is called an electrical circuit's "load". ---Nerd
What are the parts of a simple electrical circuit?
An electrical circuit is a path which electrons from a voltage or current source flow. Electric current flows in a closed path called an electric circuit. The point where those electrons enter an electrical circuit is called the "source" of electrons. The point where the electrons leave an electrical circuit is called the "return" or "earth ground". The exit point is called the "return" because electrons always end up at the source when they complete the path of an electrical circuit. The part of an electrical circuit that is between the electrons' starting point and the point where they return to the source is called an electrical circuit's "load".Contents[hide] 1 Electrical-circuits2 Electronic circuits3 Circuit-and-wiring-diagrams4 Circuit-breakers5 Ground-fault-interrupt-(GFI)-devices6 Other websites
What is the source of electrons that flow through the wire?
The battery or other power supply that energizes the circuit is.
What is the job of the power source in the circuit?
it pushes and pulls the electrons trough the circuit
What is the source of the electrons in a circuit?
The source of electrons in a circuit is supplied by an electric potential difference across two points . This potential difference in a circuit is called as voltage and is measured in joules per coulomb or volts.
Current has only one loop to flow through in a?
A: All current in a loop must return to the source. A source may feed many loops but all these loops current will return to the source as a collective. ----------- Series Circuit
What are the two common sources of electrons in a electric circuit?
The electrons are always there, for example in the metal. You don't need a special "source" for electrons in a circuit. What you DO need is a voltage source, i.e., something that pushes the electrons around.
What is the steady flow of electrons through a conductor?
The terminology for a steady flow of electrons through a conductor is called the current of the circuit.
What is through a discontinuous circuit which no current can flow?
meaning that the current from your power source doesn't return to the positive end (electricity flows from - negative, to + positive)
What is the name of a circuit which has only one loop of wire?
There are none. Electrons must flow from the source, through the circuit, and back to the source or they don't move. There are conductors other than wire, however. Best example is a car. You supply power to all the equipment in a car through wires and return the current through the car's frame. The word 'circuit' means circle and is used with electricity for this very reason.
The available source of charge that pushes a charge through a circuit is?
The available source of charge that pushes a charge through a circuit is voltage.
What is a path through which current flows?
A path through which current flows is generally called a circuit. Some might say a complete circuit to denote a "closed loop" through which electricity can leave one electrode or contact on a voltage source, travel through some conductors of some kind, and then return to the other electrode or contact on the source.
