Is a transformer one source of constant electric current?
A; Terminology is not correct a transformer is not really a source but rather a device to transform one source of power to some power that can be used as required minus efficiency of power transfer
What is the name of an electric current that flows in one direction?
That's a "direct" current.
Rate of flow of electric charge is measured in?
Electric current is the rate of charge flow past a given point in an electric circuit, measured in Coulombs/second which is named Amperes. In most DC electric circuits, it can be assumed that the resistance to current flow is a constant so that the current in the circuit is related to voltage and resistance by Ohm's law. The standard abbreviations for the units are 1 A = 1C/s.
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.
Why does the current rise when the voltage drops?
It is not generally true that current increases when the voltage decreases. Ohms law for a simple resistor says that current is proportional to voltage. However an electric motor supplying a constant mechanical load power will readjust to a lower supply voltage by drawing more current, although if the voltage is progressively reduced the motor would stall. Switch-mode power supplies also tend to draw a constant power from the supply when the input voltage changes.

What is one source of constant electric current?
Cells and batteries.A more detailed answerIn general, most power supply sources - including cells and batteries - cannot supply either a truly constant current or voltage.Because most load devices are designed to require a nearly constant voltage - and not a specific constant current. - most power supplies - including cells and batteries - are designed to supply a given output voltage whatever the current that is being drawn, provided of course that the current stays within a pre-determined designed range of output current values.One definition of "constant current source" is that it has zero output resistance, which in practice cannot exist.However, a transistor can act as a constant current source if biased and used in that manner. This can also be done using one of the several standard "voltage regulator" components - which are available from electronics parts suppliers - because they can be hooked-up to act as constant current sources to operate over a small range.
What is the biggest unit of electric charge?
The biggest unit of electric charge is the coulomb (C), which is equivalent to the charge transported by a constant current of one ampere in one second.
What part of an electrical cicuit produces the electric current?
The power source, typically a battery or generator, produces the electric current in an electrical circuit. The flow of electrons from the source through the circuit forms the electric current.
What is the path for transmitting electric currents?
Electric currents flow from the source through the circuit and back to the source in materials called conductors.
How could Theresa cause an electric current to flow through one of the copper wires studyisland?
To cause an electric current to flow through one of the copper wires, Theresa would need to connect the wire to a power source, such as a battery or electrical outlet. By completing a circuit with the wire connecting the positive and negative terminals of the power source, electrons will flow through the wire, creating an electric current.
What is a coulom?
A coulomb is the unit of electric charge in the International System of Units (SI). It is equal to the charge transported by a constant current of one ampere in one second.

How does static electric differ from current electric?
Static electricity is the buildup of electric charge on the surface of an object, which does not flow in a current. Current electricity, on the other hand, involves the flow of electric charge in a circuit. Static electricity is stationary and can discharge quickly through sparks, while current electricity flows continuously through conductors.
What is a electric current that's changes direction called?
An electric current that changes direction is called an alternating current (AC). In an AC circuit, the flow of electrons changes direction periodically, typically at a frequency of 50 or 60 Hz. This is in contrast to direct current (DC), where the flow of electrons is constant in one direction.
What is an electric current flowing in only one direction?
An electric current flowing in only one direction is called direct current (DC). This type of current has a constant flow of electrons in one direction from the negative to the positive terminal of a power source, such as a battery.
